Media importer doesn't handle tab ordering very well. #54
Description
Assuming a widget has an element reachable with the tab key, and then activating that element brings up the media importer, none of the elements in the media importer are given focus - you'd have to tab through everything else on the page to reach the media importer.
Something should probably auto-focus in the media importer. Then every widget will also probably need some way of re-focusing upon media import completion.
