A KeyUpEvent is dispatched, but the state shows that the physical key is not pressed when hitting Backspace the first time #122441
Description
I get the following error the first time I hit Backspace in a multi-line TextField:
16: '_pressedKeys.containsKey(event.physicalKey)': A KeyUpEvent is dispatched, but the state shows that the physical key is not pressed. If this occurs in real application, please report this bug to Flutter. If this occurs in unit tests, please ensure that simulated events follow Flutter's event model as documented in `HardwareKeyboard`. This was the event: KeyUpEvent#73576(physicalKey: PhysicalKeyboardKey#e6f4b(usbHidUsage: "0x0007002a", debugName: "Backspace"), logicalKey: LogicalKeyboardKey#147d9(keyId: "0x100000008", keyLabel: "Backspace", debugName: "Backspace"), character: null, timeStamp: 0:02:47.131935, synthesized)

It only happens once, and subsequently pressing Backspace doesn't trigger the error.
Steps to Reproduce
TextField(
controller: controller,
keyboardType: TextInputType.multiline,
maxLines: null,
autofocus: true,
maxLength: 40,
),where controller = TextEditingController()..text('Some\ninitial\nmultiline\ntext') that is properly disposed when dispose() is called on the widget.
Expected results:
Should be no exception
Actual results:
I get an exception the first time I hit Backspace when the widget is shown
