I'm having the same issue, but not when running astro check, it happens when editing files on Neovim.

A video is attached.

In the file in the OP, the issue is that the closing tag on line 16 has an extra space:

<a class:list={
  ['col-start-1 border-2 hover:border-primary-accent border-primary-alternative flex items-center',
   ' justify-center size-8 rounded-full', {'hidden': !prev}]
- } href={prev}> <span class="i-mdi-arrow-left"> </ span>
+ } href={prev}> <span class="i-mdi-arrow-left"> </span>
</a>

My code doesn't contain any whitespace in closing tags, so I'll investigate further.
