Recording withe the PNG codec in a MOV container no longer has a correct Alpha Channel

I use OBS on a Window 11 system to record a Browser Source with a transparent background, by selecting a MOV container and PNG codec. This always worked fine up until version 28.1.0, and it still does not work in version 29.0.0 (the background is no longer transparent), but version 28.0.03 works fine.

I have a workaround, which is to use a MATROSKA container and AYUV codec, but the files created are uncompressed and hence huge. Is there any chance of getting the MOV+PNG solution that broke in 28.1.0 working again?
