When using Lexical on the iPhone, the undo command is not working correctly, requiring two undo operations to undo one change, also happens in Playground.

Lexical version: 0.17.0

Steps To Reproduce

1. Go to Lexical Playground
2. Type 'abcde'
3. Tap undo once - 'abcde' disappears
4. Tap undo again - 'abcde' reappears
5. Tap undo once more - 'abcde' disappears
6. Tap undo again - the input is fully cleared

I suspect this issue is related to the IME behavior with the Japanese keyboard, it doesn't reproduce with the US keyboard. There have been similar reports of other IME related issues on iOS: #5841, #5629
