Events triggered out of order

Mouse down and mouse up events are triggered out of order sometimes when clicking on an input field (or contenteditable div) with the japanese keyboard selected.

The expected order should be 
1.mousedown
2.mouseup

The actual order is 
1.mouseup
2.mousedown


Reproducible steps:
1.Switch input method to japanese (Hiragina)
2.Type some text, click on the input area repeatedly.

Created a fiddle to test this (modified version of https://dvcs.w3.org/hg/d4e/raw-file/tip/mouse-event-test.html)
