Subject: [PATCH 1/1] Fix random file dialog not showing up problem.
When using QDialog to implement QPlatformDialog there will be a issue,
that QDialog will use a dummy invisible to make Qt aware that a modal
dialog exists. But for our usecase, this invisible dialog will show up
after our own qdialog and cause our dialog not accept any input.
The original workaround is to hide our dialog and show it again, but
this will hit QTBUG-48248 and our dialog will not show up at all
randomly. To avoid this, we delegate the call to show() on our
QDialog with a timer.
BUG: 350758
