Is it possible to untangle the formatting changes to make it reviewable? Either a separate commit if absolutely needed, or a different PR. I tried taking a look, GitHub's mobile UI doesn't want to load it. And scrolled a bit and didn't get to a real change yet

Agreed. That's one of the main reasons I haven't gotten through reviewing the original PR - a massive change, with formatting changes mixed in with functional changes...

If there's also other improvements that aren't related to the fix needed for your issue, and the changes can live without, it might be a good idea to not include them here too.

These are mitigation ways to help out have a PR reviewed, especially since it was stalled for years because of the difficulty of reviewing it.
