Simple Mathjax blocks with a single function call display backwards

[barillax]

This is an edge case, but I wanted to report it so you were aware (and maybe the fix is easy).

CodePen demonstrating the problem: https://codepen.io/barillax/pen/QodJPx

Summary:

If you have a block of MathJax that contains a single number with a bar over it, the number will be flipped horizontally.

I believe this is because the number gets nested inside a span with the mfliph class, but there's no additional surrounding container span that also has mfliph to "cancel out" the horizontal flipping.

You can work around this by including an "empty character" via {} directly in front of the number, as shown in the above example. For some reason, this results in a surrounding container span element with the mfliph class, which fixes the issue.

Update: this bug also manifests with a \transt{} that is by itself within a MathJax block. See screenshot below, where...

1. The first example is correct,
2. The second is incorrect, and
3. The third is correct after inserting an empty space {} directly before the \transt.

This would also be fixed if there was anything else next to the \transt, such as a period, a surrounding \textcolor, etc.

@shadinaif @OmarIthawi just wanted to call out this bug, since it might be an easy fix given how simple the workaround is above!

Thanks @barillax! That sounds like an interesting one. Not sure if we'll get to it soon. Let me know if this is a blocker issue, or if you have other issues.

@OmarIthawi no worries, the {} workaround keeps us unblocked for now!
