Hi! Thank you for biome! I am really happy at how fast it is. I have a bug report that I came across while I was experimenting with the early experimental-html formatter. I looked around some of the existing Github issues and did not find an already existing report for this though please feel free to mark it as a duplicate in case I missed something.

The bug is that the below segment:

<div attr=i-am-ok></div>
<div attr=i-have-an-extra-space another_attr></div>
<div attr=i-have-multiple-extra-spaces     another_attr></div>
<div attr=i-also-have-an-extra-space ></div>

gets formatted into:

<div attr="i-am-ok"></div>
<div attr="i-have-an-extra-space " another_attr></div>
<div attr="i-have-multiple-extra-spaces     " another_attr></div>
<div attr="i-also-have-an-extra-space "></div>

note the additional whitespace after some of the semi-colons that change the the attribute value strings to have extra trailing whitespace.

I have included a playground link here that reproduces the issue.

I am happy to answer any questions you may have/provide additional context.
