Video Player: Prevent showing the status icon on unnecessary timing

Video Player: Prevent showing the status icon on unnecessary timing

Sometimes, the status icon was shown in unexpected timing. This might be because the animation is re-fired when the dom is restyled. This patch fixes it.

BUG=none
TEST=Open window->play video->pause->close window. Repeat it 20 times and observe no issue.
