FYI -- I'm aware that a bunch of regressions from bug 1308876 turned up after it hit release (after none were reported while it was on nightly or beta).  See https://bugzilla.mozilla.org/show_bug.cgi?id=1308876#a30998038_3881 and below.  I'm going to try to look into them over the next week or two -- and hopefully there are fewer underlying problems than there are bug reports -- but these can be somewhat difficult bugs, so it might take a little time.

Makes sense to track this for 58, as we tracking some of the other issues noted in Comment 4.

I'd note that the align="left" is required, so this seems to be particular to the table floating.

This is not fixed by bug 1474771, so it needs further investigation.
