Open FileDialog in requested directory

[marbub]

In Qt Creator it is opening the protal dialog which is not using the requested directory but the shows me the recent entries. Which is not very helpful because I have to navigate by hand to the requested directory. Mostly it opens the dialog in the background too which looks like there is a bug with the dialog placement.

I think this flatpak/xdg-desktop-portal#874 is related to this. Currently FileChooser::OpenFile doesn't have such option.
