Bug: Inconsistent formatting when terminating bold inside a link [9.3 (release_9.3 @ /usr/share/emacs/27.0.91/lisp/org/)]

[Tom Alexander]

When you have a section of bold text that ends inside a link, for example:

  *can you [[http://foo.bar/][terminate *bolds* inside]] links*

Inside emacs it bolds the text "can you terminate bolds" and represents "terminate *bolds* inside" as a link, but if you export to any non-text format (I tested html, LaTeX to PDF, and ODT) then it breaks the link exporting the raw org-mode link syntax.

Expected behavior: I see three options. Naturally in HTML you can't do <b>can you <a href="http://foo.bar/">terminate bolds</b> inside</a> links so it could either

1. duplicate the bold tag:

<b>can you </b><a href="http://foo.bar/"><b>terminate bolds</b> inside</a> links

2. or the text inside a link could be considered an independent context from the outside text:
<b>can you <a href="http://foo.bar/">terminate <b>bolds</b> inside</a> links</b>

3. or the emacs rendering can be updated to accurately reflect the link being broken as it currently is in the exported output.

Reproduced the issue with `emacs -q`. Below is the version/config information:

There is only one option, per Org syntax.

The link is broken. The fontification is at fault here. This is because
its implementation cannot understand fully the syntax(!). So, you'll
encounter some glitches like this one from time to time.

Patches welcome, of course. However, the fontification will never be
perfect unless its internals are rewritten.
