[whatwg] the impact of <select>.value behavior clearing current selection prior to setting the new selection

[Jon Lee]

Hello,

A long while ago[1] there was a clarification[2] made to the html5 spec about how setting selectedIndex and value clears out the selectedness of all options prior to setting the selection. As of this writing, Safari, Chrome, Opera, and Firefox leave the selection alone if the code sets value to null or a string that does not match any of the existing options. I was wondering if anyone had any insight on impact for existing websites with this new behavior.

Thanks,
Jon
