Subject: [PATCH] HTML API: Truncated funky comments should cause the Tag
 Processor to pause.

A state change was missing in the Tag Processor when the input is too short to
find a comment closer after an opened funky comment. This patch fixes a issue
where `</#` does not correctly report incomplete input, but `</# ` does.

Developed in https://github.com/wordpress/wordpress-develop/pull/7146
