Fixed backspace being delivered after committed text on Android 12

Testing:
Enter "hello ", followed by "?" - the events generated are:
: commitText hello
: Key pressed :  scancode 11 = H, keycode 0x00000068 = H  modifiers: (none)
: Key released:  scancode 11 = H, keycode 0x00000068 = H  modifiers: (none)
: Key pressed :  scancode 8 = E, keycode 0x00000065 = E  modifiers: (none)
: Key released:  scancode 8 = E, keycode 0x00000065 = E  modifiers: (none)
: Key pressed :  scancode 15 = L, keycode 0x0000006C = L  modifiers: (none)

: Key released:  scancode 15 = L, keycode 0x0000006C = L  modifiers: (none)
: Key pressed :  scancode 18 = O, keycode 0x0000006F = O  modifiers: (none)

: INPUT Text (\x68\x65\x6c\x6c\x6f\x20): "hello "
: finishComposingText
: deleteSurroundingText 1 / 0
: Key pressed :  scancode 42 = Backspace, keycode 0x00000008 = Backspace  modifiers: (none)
: Key released:  scancode 42 = Backspace, keycode 0x00000008 = Backspace  modifiers: (none)
: commitText ?
: Key pressed :  scancode 225 = Left Shift, keycode 0x400000E1 = Left Shift  modifiers: LSHIFT
: Key pressed :  scancode 56 = /, keycode 0x0000002F = /  modifiers: (none)
: Key released:  scancode 56 = /, keycode 0x0000002F = /  modifiers: (none)
: Key released:  scancode 225 = Left Shift, keycode 0x400000E1 = Left Shift  modifiers: (none)
: INPUT Text (\x3f): "?"
: setComposingText , at 1
: EDIT Text (): ""

Previously, the backspace would be delivered after the "?"
