Popup window unable to get textInput

Popup window can not get input from the input method.

The attached demo has a normal window with a button and a text input box.

1. Click the button to pop up a red Popup window. There is a text input box on the popup window.

2. When the mouse clicks the input box and there is an input prompt, Chinese input is performed (fcitx5). The popup input box cannot get input from the input method.

3. When the input box of the normal window is clicked at this time, the input box of the normal window is in an input-enabled state and can get input from the input method.

But at this time, the keyboard event is forwarded to the Popup window. The input method input is on the normal window, but the keyboard event is on the Popup window.
