From case 670834

- Tap in input field to show mobile keyboard, then tap out to hide it: keyboard flashes and stays up (must hide manually)
- Tap to position cursor at end of text: cursor appears at beginning, but if you type, new text goes at end
- Type a bunch of text, then Backspace to remove it all: throws ArgumentOutOfRange exceptions, sometimes stops working
- Press Tab key: inserts a Tab character (!) instead of navigating to next control
- Press Ctrl A: does nothing (should select all)
- Tap to select a word: always positions cursor at beginning or end, never in middle and never selects word
- Tap Shift, then Arrow (">") several times to select a range: works fine but must press Shift again before each Arrow press
- Double-tap Shift (stays pressed), then Arrow to select a range: moves cursor but does not select anything
- Select one or more character as above, press Ctrl C to copy: COM Exception appears in VS debugger
First-chance exception at 0x756AF896 in Template.exe: Microsoft C exception: Platform::COMException ^ at memory location 0x0596EF6C. HRESULT:0x8000001D Activating a single-threaded class from MTA is not supported

- After copying, position cursor and press Ctrl V to paste: Same COM Exception occurs, text is not pasted

Temporary workaround:
Disabling Input.simulateMouseWithTouches everything works fine;
