On mobile Chrome (Android in this case), When a user has a focus on a text item (eg input), and then clicks on Media controls (<video>,<audio>). Chrome will scroll back the page to the focused item.
Demo: https://jsfiddle.net/xn0f9uv3/1/show
If I could blur the focus, the scrolling does not happen. However the audio
element does not seem to trigger any mousedown/touchstart events. The video
element triggers touchstart, but NOT if you click the play, seek or volume controls. onplay
event fires too late. onblur
event does not help.
