Desktop (please complete the following information):

Additional context This problem happen on many browsers and OSs. I think it's the Webk version problem. This issue not happen on WebA version.

I had the same issue as above By typing the first character that had Vietnamese diacritics, the input content would disappear. This issue has been happening for months now.

Same issue here. The input disappears if the first character is a Chinese character. And on my testing it only occurs on Chromium-based browsers (Edge 125 and Chrome 126), it won't happen on Firefox.

Seems like the document.execCommand API has a weird implementation on Chromium-based browsers, so Web K mitigates it by resetting the textContent to empty string of the input element.

But if I input something with IME or external app on Chromium-based browsers, an input event with empty value is triggered just between typing and entering the final word, causing the resetting procedure triggered, and the input words are removed.
