Comment 1 Marian Rehak 2022-02-14 15:13:27 UTC 
Created vim tracking bugs for this issue:

Affects: fedora-all [bug 2054279]
Comment 2 juneau 2022-02-14 16:37:04 UTC 
Marking services affected/wontereport/low as this is yet another in a long line of vim issues that are very unlikely to affect services, and remediation for vim is already in play.
