@troian ah yeah, no worries then, I'll do a sprint myself to create backport PRs for the ones before this one 👍. Putting this to draft for now.

Is there a corresponding PR for this fix in master already? I'm struggling to find what this relates to. Ideally this should be merged into master and then backported to the release/v0.41.x branch, right?

Unfortunately I cannot seem to get a consistent test running, I've been running those in ubuntu docker (same as the one in the CI), but I keep getting different test fails. Unfortunately I cannot even debug it, apparently, as the target build system is linux and setting up a dockerized debugger is too complex with win-docker.
