We keep getting reports where users claim they would run into **more** edit conflicts recently. These reports are not about "conflicts with myself" (see T222805 as well as T72163 for that). More than one user said the conflict was with an edit that was made hours before.

To do:
[] Check tickets in T72163 and #mediawiki-page-editing (there is an "Edit conflict" column) for closed or in-progress tickets that might be related to conflict detection.
[] Check the Git logs for the relevant code. Are there recent changes that could be related?
