MD037 false positive with emojis containing odd number of underscore on same line

[EnigmaTriton]

For example

:ballot_box_with_check: _Somewhat important task_

gives a warning for _check: _ while the line is perfectly recognized by VSCode (and obviously github) as:

☑️ Somewhat important task

I can work it out using asterisks (or :white_check_mark: which contains an even number of underscores for this exact purpose) but I tend to use _emphasis_ and **strong** to make it more obvious when editing source so this issue is slightly annoying.

On the other hand I'm not sure that emojis are part of the Common Mark specification so it might be an improvement request or even downright invalid request.

Please see #324 for a discussion of this kind of issue.

In this case, ignoring words with internal _ would seem to help. I'll look for a way to do that without compromising the rule.

Oh sorry, I searched for issues on MD037 but I probably forgot to remove the is:open part.

Much clearer, thanks and if you can take it into account anyway, then great. 👍
