Steps to reproduce:
1. Open a project in 5.5+
2. Try to change windows keyboard language with shortcut(Shift + ctrl OR shift + alt, depending on your configuration)

Expected result: keyboard language changes
Actual result: keyboard language does not change

Manually pressing and changing keyboard language still works.

Reproduced on 5.5.0a1, 5.5.0b4, 5.5.0b5
Regression found in 5.4.1p3
Bug first appears in 5.5

NOTES:

- Some developers are able to reproduce the problem with only release builds on their machines, but NOT debug builds.
- When the bug is happening, the language toggle is getting queued and not actually released to the OS until the window is moved. For example, toggling language once and then moving the window WILL make the language change.
