Format unquotted attributes adding quotes to already quoted attributes

[IbraheemTuffaha]

The newest release of v0.7.1 by @x4d3 introduced format unquoted attributes.
In some cases, it's adding quotes to attributes that already have quotes, check the image below 👇

Seems to me like a weird edge case that needs to be handled.

To add some additional context, it appears to be happening on attributes that contain an = sign and are of at least a certain length (somewhere in the 50-60 character range?). I was able to have it happen on <a> tags but only if the URL was of a certain length.

Happens for this line as well:
