It appears that the parser doesn't recognize template syntax in attribute part. This is likely the same issue as #183.

Seems like the comments are also broken when placed as attributes and keep_comments=True

I am experiencing this problem as well with the sailfish syntax. My command, input and output are shown below.
command
minhtml --keep-closing-tags --preserve-chevron-percent-template-syntax input.stplinput.stpl
output
There seems to be clever ways to progressively work around the issue. For example, removing the space before the template closing tag prevents some of the distortion highlighted in the earlier example, and I can actually get the above code to work if I change the order of the attributes. However, none of those fixes feel elegant and reliable. It feels like relying on quirks in the code. I am also not sure if any of this is intended behavior, so I am hoping that someone more familiar with the project could offer some guidance here.
