Details

This is more of a heads up since it's actually a bug in lightningcss tracked here:
parcel-bundler/lightningcss#805

The report over there also contains a reproduction. I'm opening this issue with the goal of raising awareness about this issue, and also to ask if the option exists to bring the SWC CSS minimizer back.The SWC minimizer seems to be a bit more conservative which makes breakages such as this one less likely. Of course fixing lightningcss would probably be even better... :-)

Also, having an issue in the rspack repository may help others who are running into the same problem.

The bug was introduced between 0.7.5 and 1.0.0-alpha.0.
