PressKey does not add the keys into a focused input field

- Tested using Inspector v 1.4.0 and AUT v 1.7.0

### Actual result
In Inspector/tests when using `Click/Press` action (Inspector) / `PressKey` command (AUT) keyboard keys could not be added in a focused input field
- _Workaround_: the action can be performed only in tests using the `SetText` command
