document whose root element is display:none can't take focus
This is split off from bug 283686. A document whose root element is display:none can't take focus, and seems to break focus/tabbing stuff. Steps to reproduce: 1. load attachment 175578 [details] 2. click in the location bar 3. hit tab twice (or three times if you have tabs in the browser) 4. hit Shift-tab twice (or three times) to reverse Expected results: 3. document has focus outline 4. focus is back in location bar Actual results: 3. no focus outline 4. no focus outline
On my Mac (10.5.6), with that testcase most keyboard shortcuts fail - the only one that works is Cmd+H (hide the app).
ccing mats, and especially enn (since he's rewriting focus anyway).
Do we want to make the document focusable, or make the document non-focusable, and remove it from the tab order? There's no frame to draw the focus ring (I assume) nor one to fire key events at, so I assume the latter. What should happen when clicking the empty document area?
Ideally I think the document should be focusable, but I don't think it matters a huge amount. There's still a viewport frame and canvas frame, I'd think, although one or both might have null mContent...
The focus outline still appears not to be drawn, although keyboard shortcuts now appear to work again.
