That's certainly what I would do. There are four workarounds listed at
https://bugs.launchpad.net/oem-priority/+bug/1842320/comments/125
three of which seem simple: MODULES=dep, COMPRESS=<whatever works best>,
and GRUB_GFXMODE. Have you tried any of these? Do they fix things?

Well, you don't say what it is you want to learn. If it's about
Grub, the fix is already in, AIUI, and can be read about at:

https://git.savannah.gnu.org/cgit/grub.git/commit/?id=012fe7f0550899a2f1cf2fcf48f29ecf4820f880

Applying the patch to the source and recompiling for your version of
the OS would seem to be a complete waste of effort, unless you've
exhausted the three workarounds.

I have no idea whether there's any intention to fix Grub in bullseye
at this late stage. As for upgrading your installed system, I assume
that you can upgrade it to 11.6 in the usual manner. If any firmware
has changed between 11.5 and 11.6, it'll be upgraded in just the same
way. (For the packages I've looked into, upgrades usually just add
more blobs, rather than changing any that are already present.)

Cheers,
David.
