fixed stuck double tap

Issue Description

• Problem: The seek buttons in the video controls were incorrectly remaining hidden while still registering clicks.
• Cause: This behavior was due to both _hideSeekForwardButton and _mountSeekForwardButton being set to true at the same time. The root cause of this issue was traced back to the TweenAnimationBuilder's end value being set to zero which prevents onend from being called.

Proposed Solution

• Fix Implementation: The proposed fix involves a minor yet critical adjustment to the TweenAnimationBuilder.
• Details:
  • Change the end value from 0.0 to a minimal non-zero value (0.000001).
  • This adjustment allows the 'on end' callback to be called to hide and unmount the UI elements.

used animated opacity and timers instead, since the bug still happens and not nothing resets it. :(
