           Summary: Adobe Illustrator CS6 (16): Cannot type into text

WINEDEBUG=gdiplus trace of opening and attempting to interact with the
collapsed panel text input

Reproduction:

1. Create a new document (Ctrl+N)
2. Ensure Character panel is docked in a collapsed state:
   a. From main menu, Window -> Workspace -> Web
   b. Open the collapsed Character panel by clicking on its icon or by hitting
Ctrl+T
3. Focus any text input control in the panel (e.g. the font family)
4. Mash keyboard

Expected: Text is entered into the control
Actual: Nothing is entered into the control

With native gdiplus, this works correctly. It seems like with native gdiplus,
focusing the text field in a collapsed panel causes Illustrator to create a
whole duplicate window overlaying the panel which is actually receiving the
text input.

I have attached a gdiplus trace containing just the part where the panel is
opened and then keyboard input is attempted. Please let me know what additional
information you need.
