Search modules keyboard input produces duplicate of input key

Version Tested: SHA builld - 4a85fc8

Expected:
Rick click to open dialog for adding module
Type "a" to see all modules starting with "a"

Actual:
Type "a" and get "aa".

Just FYI - I confirmed double lettering was not happening on Rack2 official release.

This is on Windows, correct?

Keyboard input in Windows is host-dependent with a variety of weird behaviors.

So far:

• Reason 11: Behaves as if the Shift key were stuck, only uppercase and no spaces
• Renoise: Won't accept keyboard input even after the keyboard is explicitly enabled in renoise's ui
• VSTHost: Text fields add a letter on key down and on key up both

To explain, this is because VST2 defines a method for hosts to notify plugins of keyboard events.
But typical of things in VST, exactly how to implement is not documented well so every host does it a bit differently.

Some hosts do not send the special VST2 keycodes at all, only relying on native OS events.
Others send both.
And finally a few ones only send VST2 keycodes, never OS events.

The whole thing is quite silly and PITA to implement and get right...

Can happens in Reaper on Windows for me but Ableton is fine.
