While having set hide tabbar on single tab to true opening the second tab
resizes the innerHeigth of the first then tabbed window but there is no onresize
event fired. Manually resizing the window fires to the first window on tab
switchback only if the resizing makes the window bigger?!
Under 45244 it was reported that the unfocused window doesn't receive the onresize
event at all - this is only true for me if resizeing makes the window smaller -
if it becomes bigger the event is fired on switch back to the first tab.
Same on firefox

Reproducible: Always

Steps to Reproduce:
1.Set hide tabbar on single tab
2.load page which reacts to onresize
3.open new tab

Actual Results:  
the onresize event is not fired to the first window
so relayout is not possible

Expected Results:  
The onresize event should be send to the first tab at least on switch back to it

This is a dupe. If you could perhaps provide a testcase (minimal page making use of onresize) for the bug of which this is a dupe, it would be appreciated.
