Improper emoji rendering with v5.1.0

[davidsandoz]

Marked version: v5.1.0

Describe the bug
Emoji rendering fails if located at the beginning or the end of a bold text.

I don't know if this is specific to the bold markup or if the issue happens with other markup.

Additional note: It works well with v5.0.5, so this got introduced with v5.1.0.

@calculuschild Looks like this might have been broken by #2841

Are emojis considered punctuation or ?

[UziTech]

I don't think these emoji are in \p{P}. It looks like it is not all emoji that are the problem. This is only happening to certain emoji.

@calculuschild I've been trying to get this to work with \p{P} but I don't know if we can. I think the best fix is to revert #2841.
What do you think?

[calculuschild]

We can revert if needed, but it fixed several other cases too so we would lose those fixes.

Are emojis considered punctuation or ?

What I meant by this is are emojis meant to be treated as punctuation according to the Commonmark spec?
