Android: Using Samsung "Smart Typing" with Quick Controls 2 TextField or TextInput causes backspace button to commit the currently edited text instead of removing a letter

When using Samsung device with "Smart Typing" enabled in Quick Controls 2 TextField or TextInput, pressing backspace button commits the currently edited text to the cursor position instead of removing a letter.

This does not happen with controls 1 TextField. Also with Android 4 the issue does not reproduce (it reproduces with anything more than 4). Only reproducible with Samsung devices.

Steps to reproduce:

• Run attached sample
• Write an e-mail to the textfield without finishing it (so smart typing feature is still enabled)
• Move the cursor to any position in the middle of the written e-mail
• Press backspace button to remove a letter
• EXPECTED: Letter is removed
• ACTUAL: The current text of the textfield is commited to the cursor position

Reproducible at least with these devices:
Galaxy A5, Android 8
Galaxy S8 (Edge), Android 8
Galaxy Tab S2, Android 7
Galaxy S9+, Android 8
Galaxy S7, Android 8, Samsung keyboard 3.0.24.17 (not happening with other keyboards)
