I can't reproduce this with the latest focal daily -- I followed the instructions from comment #2 as closely as I could UEFI, selecting install from boot menu, french language, french keyboard, custom partitioning, and the layout was still active in the user creation screen. It was a VM rather than real hardware but if that matters I'm going to cry :)
Let me know if there is a way to reproduce and I'll look into it.
