ox-html Incorrectly (?) Puts HTML Into the `<title>` Tag

Hi all,

I noticed over the weekend that the `<title>` tag in an ox-html document is
populated with HTML when inline formatting like bold or italics is used.
I'm running org 9.4.4 but even on HEAD
<https://code.orgmode.org/bzg/org-mode/src/9ea7ff5e2f8f9f280f8022cade62c1a3bba1478c/lisp/ox-html.el#L2092-L2111>
this
behavior seems to be the same where `(org-export-data title …)` is used to
populate the title rather than something that would render the title
textually.

My understanding from MDN
<https://developer.mozilla.org/en-US/docs/Web/HTML/Element/title> is that
`title` tags should never contain markup.

Is this something we'd take a patch for? My thought is that the title
should be converted using the text backend by default, perhaps with a
configuration variable that would let you specify a different one (for
instance markdown) but I wouldn't go that far at first. Of course at
minimum since org is textual it could just use the title without exporting
at all but I think that doesn't go far enough. The other possibility would
be to somehow strip all special characters from the title but I think that
goes much too far.

Thanks in advance!
