This PR fixes that the placeholder text is not removed when IME is activated.
Problem
When the preedit window is opened, the placeholder text is not removed. This is weird because the text input is already editing the content but the placeholder text is still there.
before.mp4
Solution
This PR removes the placeholder text when the input method is activated even if the text input content is not committed. This is the same behavior as
<input>
element of web browsers.after.mp4
