Twitcher leaks pressed Tab-key to previously activated window

[idefix]

When you open Twitcher by holding Ctrl-Tab for a second, the previously activated window gets the Tab-key signals until you release the Tab-key.
Tested with Haiku hrev29463.

Steps to reproduce:

• Open a Terminal window or a Tracker window
• When that window is activated press and hold the Ctrl-key and then press and hold the Tab-key
• After a second, the Twitcher window opens
• Immediately after opening, the previously activated window react to a continuously pressed Tab-key:
  • A Terminal window displays: "Display all 501 possibilities? (y or n)"
  • A Tracker window displays a moving file selection

• Release the Tab-key (but not the Ctrl-key)
• Press the Tab-key again:
  • The application-selection in Twitcher changes, but the previously activated window won't react to the Tab-key anymore

Preferred behaviour:

• The previously activated window shouldn't react to the pressed Tab-key
