Best guess at an appropriate component.

Edgar: as this seems to affect only one website or potentially a not super-popular JS library (https://github.com/GianlucaGuarini/Tocca.js/), I'm inclined to set severity to S3 and prioritize it as P3. Since you're more familiar with touch events, please check if you consider this more important.

S3 sounds reasonable., thanks.

Hmm, yeah, there is only mousemove event fired on the video element, maybe the mousedown/up or click events are blocked by video control on Fenix? Move to Audio/Video: Playback, feel free to bounce it back if I am wrong.

This seems to affect youtube on firefox android ,so you need to change priority to fix
