I wouldn't call this a bug at all. The specs clearly advise developers to
avoid doing this.

"White space is not permitted between the markup declaration open
delimiter("<!") and the comment open delimiter ("--"), but is permitted
between the comment close delimiter ("--") and the markup declaration close
delimiter (">"). A common error is to include a string of hyphens ("---")
within a comment. Authors should avoid putting two or more adjacent hyphens
inside comments."

<tip type="HTML comments DON'Ts">
DO NOT
a) Place spaces in the opening delimiter of the comment.
b) Use two or more adjacent hyphens as part of your comment.
