Actually, I think it turned out that this move wasn't necessary after all -- I had meant to revert it before committing. I'll do so now.

Looks good to me! 👍

Do we have any idea why forcing an italics class was initially needed? Or was it just a bug?

In the context of STIX falling back to Bakoma, it needs to be hardcoded to it because the symbols the fallback was needed for are only in it. I think this was copied-and-pasted to the context of DejaVu falling back to STIX, where that is not the case.

Are there no italic numbers? 05 vs 15?

I also wonder what is wrong with the baseline of the 't'.

@QuLogic: That's correct. There are no italic circled numbers. Not sure what you mean by "05 vs. 15"

The baseline of t is a larger issue (addressed by #5414, but it will be some time to get that done). But that's not introduced by this PR.

No, I didn't mean circled, just plain italic numbers, e.g., mathfont_dejavusans_05.png vs. mathfont_dejavusans_15.png specify mathrm vs. mathit. But I see this is the case for the other fonts as well.

Yes -- there are no italic numbers in any of these fonts.
