Sorry, I don't know what "doh!" means. Did I something wrong? I'm German and not a native English speaker. I tried my best, to make the bug report as understandable and as usable as I could. Sorry if I made a mistake 🥺

I am only able to reproduce this in Blender 2.91,

note: might be related to #79568 (EEVEE Film transparent not working)
