Details:

This is a weird one. It seems as though tex4ht accidentally introduces unicode
character U+0304 into the middle of the mathml when it encounters \bar.

In ht-bar.tex, I have 'Y = \bar{X}'.

I compile this by running make4ht -uf html5 ht-bar.tex "mathml,". The relevant
bit of the mathml in the output is:

<mover accent='true'><mrow><mi>X</mi></mrow><mo accent='true'>̄</mo></mover>

Over there towards the end of the line is >, combining macron, <.

Firefox renders this just fine, but this seems a bit weird, and the W3C
validator also complains about it (with a 'warning') - which is how I noticed
this.
