TypeError: h is not a function

[hugovicfortman]

This issue is also experienced in other vue libraries when upgrading to vue 3.
Since the h renderer function is no longer auto injected, it is not recognised as a function when invoked.

 render (h) {
      const data = {
        staticClass: 'icon md-icon md-{{icon}}',
        'class': this.className,
        attrs: {
          width: this.width,
          height: this.height,
          viewBox: this.viewBox,
          xmlns: 'http://www.w3.org/2000/svg'
        }
      };

      return h('svg', data, [
        h('path', {
          attrs: {
            d: '{{path}}'
         
          style: {
            fill: this.color
          }
        })
      ])
