The placeholder is not hidden when getting the focus

hello;
First of all, you switch to the Chinese input method, input a few characters, delete these characters, and switch to the English input method, input a few characters, and the placeholder does not disappear. cmEditor.on('change',callback) Event not captured
Codemirror version is 5.61.0。
The reason is that "inputStyle" is set to "contenteditable"

CodeMirror.fromTextArea(this.$refs.cmEditor, {
  inputStyle: 'contenteditable',
})
