Safari 16 Preventing Sleep on Big Sur

[NajamQ]

I don't know if it's a bug. com.apple.safarishared.WBSParsecDSession.autoFillDataUpdate is always the cause of keeping the computer from sleeping automatically.

I tried clearing Safari Cache and it worked for a while, then again it started to prevent sleep.

Assertion status system-wide:

BackgroundTask 1

ApplePushServiceTask 0

UserIsActive 1

PreventUserIdleDisplaySleep 0

PreventSystemSleep 0
