I'm seeing a number of test failures currently:

4 files contained unexpected results:
  lisp/textmodes/tildify-tests.log
  lisp/textmodes/reftex-tests.log
  lisp/gnus/mml-sec-tests.log
  lisp/electric-tests.log

I didn't think they had anything to do with this, but:

Test tildify-space-undo-test-tex backtrace:
  nil()
  tex--redirect-to-submode(#f(compiled-function () (interactive nil) #
  apply(tex--redirect-to-submode #f(compiled-function () (interactive 
  tex-mode()
  funcall(tex-mode)

in

3 unexpected results:
   FAILED  tildify-space-test-tex
   FAILED  tildify-space-undo-test-tex
   FAILED  tildify-test-tex

I haven't checked whether all these failures are related to this,
though.

(This is --with-native-compilation, if it makes a difference.)
