For ℝ, "emacs -Q" uses "Latin Modern Math" and "emacs" with customizations uses
"XITS Math".
For ≤, both use Ubuntu Mono. I changed the default font and noticed slightly
different glitches, including with a variable-pitch font multiple "!"
disappearing.

More investigation suggests that the problem only happens when both parts of
the composition are not displayed with the same font. For example, if I set my
default font to Latin Modern Math, the problem goes away.

Apt tells me these packages are up-to-date, but it might not be offering me the
very-latest version:
$ apt show libotf0
Package: libotf0
Version: 0.9.13-3
$ apt show libm17n-0
Package: libm17n-0
Version: 1.7.0-3
$ apt show m17n-db
Package: m17n-db
Version: 1.7.0-2
