What did you do?

i need to go to work now, so i try to describe it as fast as i can. https://ponylove.cc/#vid-812 set audio language to german in the player, make sure forced german subtitle is active. song starts around 3:20, and subtitle will be active for that section. if one now hovers repeatedly over the player and the controls show and hide repeatedly (i know that most people will not do that thought), it happens that some subtitles mix up. like shown in the picture. the subtitle file is checked, and its according to the specification for vtt files. some subtitles/cues are back to back thought, but also according to the specification. no overlap under specification. this shouldn't happen.

What did you expect to happen?

no overlapping / mixed up subtitles.

What actually happened?

subtitles suddenly are overlapping / mixed up like shown in the picture. happens with hovering back and forth over the player repeatedly.
