Type some text and tap the custom clear button, and then programmatically return focus to the input, I won't be able to continue typing. The caret is blinking, but I can't input anything when I type on the soft keyboard. This happens on a Japanese keyboard and cannot be reproduced on an English keyboard.

Thank you for the test case!

I am able to reproduce the bug with IME on iOS 14 beta (testing with both Japanese Kana keyboard and Chinese Pinyin). It looks like WebCore::Editor's composition state is out of sync with system keyboard state, which seems to cause problems.
