This seems to happen because of the <div> just above the button and input elements (class="_26oo") gets a style width:0px. The value of width seems to be set programmatically and switching tabs causes this to get recalculated. The value it calculates is sometimes 0 but switching tabs shows this to be flaky, working sometimes. This implies some kind of timing issue when querying page geometry. As best I can tell, this is calculated on some video plugin "TimeSlice" event so I think it's essentially a timer. I'm not sure where the width value is coming from since it's part of the React framework but I'm guessing whatever value it's querying is 0 until we focus the tab.
