During truncate marker initiailisation on a secondary, the PBWM lock is acquired in MODE_IS by default.
A deadlock can happen as follows:
- There is a large prepared transaction, the primary waits for the commit to be replicated
- The OplogApplier on the secondary tries to apply a new batch with the commit, but needs to acquire the PBWM lock in MODE_X
- The ChangeStreamExpiredPreImagesRemover initialisation acquired the PBWM lock in MODE_IS, but gets stuck waiting for the prepared transaction to commit or abort, but it can't because it needs the PBWM lock.
