Description

If Auto Scroll is enabled, event track can't  trigger, so events may not fire. The frame numbers appear to be duplicated. Especially noticeable when the [View Range End Time] is small value (Working Auto Scroll).

Steps to Reproduce
  1. Create new actor and add custom event what exec PrintString.
  2. Create new level sequencer and add actor made in step 1.
  3. Add event track and add key to trigger custom event of step 1 every second.
  4. Enable auto scroll in sequencer.
  5. Decreasing value of "View Range End Time" with Ctrl+Scroll wheel up. (because working auto scroll)
  6. Play in editor by simulate.
  7. Play level sequencer.

 

Expect:

Custom events always fire and output log every second.

Result:

Some custom event can't trigger.

 

Reproduced when play sequencer after simulate attached project.
