1096735 - Select elements from within shadow dom don't get input method context changed events

This is because the events are re-targeted to the shadow dom room. We need to use originalTarget.

Attachment: Use originalTarget for detecting focus/blur of input elements.

WIP - need to check that mochitests pass and write another one.

Shadow DOM isn't a device interface, retargeting component.

This seems to prevent screen readers from reading the items in the select list via arrow keys.

See test here:

http://richcaloggero.github.io/test/select-shadow.html

There are two `select` elements on the page, first one in normal "light" dom, second in shadow dom. Focus on each in turn with a screen reader like NVDA running and arrow through each select list.

The one in light dom should announce it's items as you move through with arrows; the one in shadow dom does not.
