Situation: A window instance with a text input can be shown multiple times.
Problem: Setting the text of that window’s text input the first time will correctly display the text. But setting a different text before opening the window the second time still shows the text from the first time, but reading the text input returns the correct text.
The same problem occurs with text areas.
The demo app shows this behavior, the 2nd time you need to enter a different text to open the window again.
