This should now be fixed in Emacs 28.  I think the current logic of
shortening the padding when it's spaces is fine -- we're a bit sloppy
when defining comments, so they're "<!-- " in html-mode, and the padding
is " ", but we don't want extra padding in that case, so
comment-padright/left shortens it.

But if the padding isn't spaces, then it shouldn't do the shortening, so
I've made that exact change.
