Steps to reproduce:

Honestly I'm not even sure. I will attach an example.

For some context: This is a regression with recent nightly builds (present in both 20210518094531 and 20210518160751, possibly older ones too). It does not happen with neither dev edition(89.0b13) nor stable(88.0.1).

Actual results:

Most of the text only had transform applied once. The text ends up being flipped.

Expected results:

Transform should apply twice. None of the text should be flipped.
