How to reproduce:

1. Open attached project
2. Build to Standalone and run
3. Select the Input Field
4. Press CMD + Left Arrow
5. Type in a specific sequence of symbols (for example '12345')
- Note that it comes out backwards (54321) and the cursor remains to the left of the sequence
- Certain functions don't work at all (Fn + Backspace for Delete is detected, but the Input Field does not respond)
- This works fine in the Editor

- Reproduced in Version 5.4.0b10 (d5987c96f84a), Version 5.3.3p3 (1c43f6d3d3c3), Version 5.2.4f1 (98095704e6fe)

- A workaround is to create a script that implements the Delete, Home, End, PgUp, PgDown functionality manually.
