Folder selection doesn't work in flatpak Krita

[geekley]

The "Set References Folder" button doesn't use a proper open dialog on flatpak Krita. It uses the file selection instead of directory selection, so I can't select a folder (and selecting a file doesn't work either). This is probably a bug in Flatpak/Qt related to portals.

However, the issue is solved for me when disabling native open dialogs with QFileDialog.DontUseNativeDialog:
photobash_images_docker.py#L452

    def changePath(self):
        if self.directoryPath == "":
            path = QStandardPaths.writableLocation(QStandardPaths.PicturesLocation)
        else:
            path = self.directoryPath
        dialogOptions = QFileDialog.ShowDirsOnly | QFileDialog.DontUseNativeDialog
        title = "Change Directory for Images"
        self.directoryPath = QFileDialog.getExistingDirectory(self.mainWidget, title, path, dialogOptions)
        Application.writeSetting(self.applicationName, self.referencesSetting, self.directoryPath)
        # [etc...]

First of all, thank you for the report! I haven't been on Linux in a while, so I'm going to test this in another OS, and if nothing fails, trust that it does indeed fix the issue. I'll try to add this today, and create a new bug fix release.

Thank you for your diligence!

Cool! By the way, it'd also be nice if middle-clicking an image opened it in a new tab, like in browser links (I see that the option is already there when you right-click it).
