Nested if else blocks are not properly indented

[Tofandel]

Reproduction

=ltr-property($property, $spacing, $deprecated: null)
  @if $deprecated != null
    $pos: "left"
    @if $deprecated
      $pos: "right"
    @warn "The third argument of ltr-property was deprecated, use the full name of the property instead"
    +ltr-property($property+"-"+$pos, $spacing)
  @else
    @if $rtl
      @if str-index($property, 'left')
        #{str-replace($property, 'left', 'right')}: $spacing
      @else if str-index($property, 'right')
        #{str-replace($property, 'right', 'left')}: $spacing
      @else if str-index($property, 'border-radius')
        @if type-of($spacing) == 'list'
          @if length($spacing) == 2
            #{$property}: nth($spacing, 2) nth($spacing, 1)
          @else if length($spacing) == 3
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 2) nth($spacing, 3)
          @else if length($spacing) == 4
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 4) nth($spacing, 3)
          @else
            @warn "Invalid usage of ltr-property"
        @else
          @warn "Invalid usage of ltr-property"
      @else if type-of($spacing) == 'list' and length($spacing) == 4
        #{$property}: nth($spacing, 1) nth($spacing, 4) nth($spacing, 3) nth($spacing, 2)
      @else
        +ltr-property($property, $spacing, true)
      //Warn of deprecated use
    @else
      @if not str-index($property, 'left') and not str-index($property, 'right') and type-of($spacing) != 'list'
        +ltr-property($property, $spacing, true)
        //Warn of deprecated use
      @else
        #{$property}: $spacing

When lint fixing this file the output is

=ltr-property($property, $spacing, $deprecated: null)
  @if $deprecated != null
    $pos: "left"
    @if $deprecated
      $pos: "right"
    @warn "The third argument of ltr-property was deprecated, use the full name of the property instead"
    +ltr-property($property+"-"+$pos, $spacing)
  @else
    @if $rtl
      @if str-index($property, 'left')
        #{str-replace($property, 'left', 'right')}: $spacing
      @else if str-index($property, 'right')
        #{str-replace($property, 'right', 'left')}: $spacing
      @else if str-index($property, 'border-radius')
        @if type-of($spacing) == 'list'
          @if length($spacing) == 2
            #{$property}: nth($spacing, 2) nth($spacing, 1)
          @else if length($spacing) == 3
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 2) nth($spacing, 3)
          @else if length($spacing) == 4
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 4) nth($spacing, 3)
          @else
            @warn "Invalid usage of ltr-property"
@else
          @warn "Invalid usage of ltr-property"
      @else if type-of($spacing) == 'list' and length($spacing) == 4
        #{$property}: nth($spacing, 1) nth($spacing, 4) nth($spacing, 3) nth($spacing, 2)
      @else
        +ltr-property($property, $spacing, true)
      //Warn of deprecated use
    @else
      @if not str-index($property, 'left') and not str-index($property, 'right') and type-of($spacing) != 'list'
        +ltr-property($property, $spacing, true)
        //Warn of deprecated use
      @else
        #{$property}: $spacing

Notice how one else block lost it's indentation, this then causes a parse error

Edit:

Additional information, it seems this is caused by the warn block, I have found a workaround

Workaround

=ltr-property($property, $spacing, $deprecated: null)
  @if $deprecated != null
    $pos: "left"
    @if $deprecated
      $pos: "right"
    @warn "The third argument of ltr-property was deprecated, use the full name of the property instead"
    +ltr-property($property+"-"+$pos, $spacing)
  @else
    @if $rtl
      @if str-index($property, 'left')
        #{str-replace($property, 'left', 'right')}: $spacing
      @else if str-index($property, 'right')
        #{str-replace($property, 'right', 'left')}: $spacing
      @else if str-index($property, 'border-radius')
        @if type-of($spacing) == 'list'
          @if length($spacing) == 2
            #{$property}: nth($spacing, 2) nth($spacing, 1)
          @else if length($spacing) == 3
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 2) nth($spacing, 3)
          @else if length($spacing) == 4
            #{$property}: nth($spacing, 2) nth($spacing, 1) nth($spacing, 4) nth($spacing, 3)
          @else
            @warn "Invalid usage of ltr-property"
            //We need a comment here or linter poops itself
        @else
          @warn "Invalid usage of ltr-property"
      @else if type-of($spacing) == 'list' and length($spacing) == 4
        #{$property}: nth($spacing, 1) nth($spacing, 4) nth($spacing, 3) nth($spacing, 2)
      @else
        +ltr-property($property, $spacing, true)
      //Warn of deprecated use
    @else
