Testcase 2 (sources + binaries)

I'd like to reopen this bug. I can confirm the behavior has changed and is
better than it used to be, but it's still not perfect (ie: it still doesn't
match the .NET one).

Here's a second testcase that shows a subtle issue not covered by the first
testcase. It has a TreeView with 3 Nodes. Only the first Node can't be
selected. If you select the 2nd or 3rd Node, then try to select the first Node,
the selected background color (which is grey here) will no longer be there
behind the selected Node. You can still see which Node is selected only thanks
to the dotted focus rectangle, but the selected background color should still
come back once you've released the mouse button pressed over the unselectable
Node.
(I'm not sure why, but in my own app, there is no focus rectangle at all, so
the background color is the only way to tell which Node is focused)
