Issue is fixed in f34 as well, do you have a reason not updating to f34 ?

Comment 2 P D 2021-02-17 11:01:22 UTC

My issue was posted multiple times due to bugzilla glitch.

I plan on updating to Fedora 34 when it is released, but it is currently not even in beta.

I do not see this as a priority issue, as it is fixed in f34 and workaround exists. Closing this issue as WONTFIX.
