Description
An application creates a background worker thread (QThread) to handle permanent communication tasks. When the UIThread opens a OS native (modal) FileDialog with the
QFileDialog.getSaveFileName() or QFileDialog.getOpenFileName()
call not only the UIThread is blocked but also the background thread.
Expected behavior: Background threads run execution while a OS native (modal) FileDialog is opened.
However, the attached Code example works under PyQt6 as expected.
