That bug was about doom-modeline and similar extensions, and it was
never fixed (because we found the solution to be elusive and nowhere
near simple), so it's small wonder the issue still exists.

Is there something new you see that you think will help us in dealing
with this problem?  If so, could you please describe the new
information?

Thanks.
