Unquoted single char values are not handled properly

[x4d3]

Currently this files

<div
  class="col-12 autocomplete"
  data-controller="autocomplete"
  data-autocomplete-min-length-value=2
>
</div>

is being transformed to

<div
  class="col-12 autocomplete"
  data-controller="autocomplete"
  data-autocomplete-min-length-value=22
>
</div>

Which looks like it's caused by this line

erb-formatter/lib/erb/formatter.rb

Line 148 in 183125e

full_attr = "#{name}=#{value[0]}#{value_parts.join(" ")}#{value[-1]}"
