Tamius Han e1e962df04 If no element fits the criteria for the video player, have extension ignore such videos.
Also, sometimes mutationObserver doesn't catch all mutations/we miss some mutations. Added a delay that validates offsets. If validation fails, retrigger aspect ratio correction to make sure there's no misalignments. (That last bit was mostly needed for new reddit)
