Specifying keys in the config breaks multikey hints

[gerazov]

When specifying keys the two-letter hints don't work, i.e. one-letter hints are shown instead which are shown again afterwards - so there are multiple single-letter hints of the same value.

Here I do hop line without specifying keys and then reloading the config with the specified keys:

require'hop'.setup({
      keys = 'asdfjkl;qwerghuiopzxcvnmjtyb'
      })

I'd like to change them because in the defaults:

       keys = 'asdghklqwertyuiopzxcvbnmfj'

The g (and h) are quite in front and ; is missing.
