Same post: https://stackoverflow.com/questions/63527069/ios-safari-input-typing-issue-when-clear-value#comment112334984_63527069 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. demo: https://codepen.io/fellows3/pen/vYGyjjV

Created attachment 407018 [details] Repro case by fellows3 (In reply to fellows3 from comment #2) > More reduced test case: https://codepen.io/fellows3/pen/WNwoygO 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.
