Revert cf6aaf37a4, causing false OOS in visual replays.

cf6aaf37a4 fixed #5546, but it seems to cause some rare OOS in visual
replays, as reported in #5909. The culprit is likely that hashes aren't
computed at quite the same moment and onDestroy changes things.

Reverting for now before A24.

Reported by: Angen
Refs #5546.
Fixes #5909

This was SVN commit r24764.
