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 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) : Key released: scancode 18 = O, keycode 0x0000006F = O modifiers: (none) : Key pressed : scancode 44 = Space, keycode 0x00000020 = Space modifiers: (none) : Key released: scancode 44 = Space, keycode 0x00000020 = Space 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 "?"
