DPAD ui navigation - dispatchKeyEvent doesn't reset the timer for hiding player controller

[sviety]

[REQUIRED] Issue description

I'm updating exoplayer version in my TV application from 2.6 to the newer version (2.9+) and i noticed that during navigation using DPAD PlaybackControlView auto hide timer is not being reset on key events.
Older version (2.6) was working properly - PlaybackControlView was being hiden after few moments since last KeyEvent. I'm using simmilar implementation as demo applcation for handling key events, so the dispatchKeyEvent method in Activity is handled in a same fashion.

[REQUIRED] Reproduction steps

Use demo application on devices with AndroidTV and use DPAD to navigate on player components.
