Filepicker invoked through xdg-desktop-portal requests directory instead of files

[sylph1o]

Steps to reproduce

Configuration

I use xdg-desktop-portal to define my file chooser for the applications that support it. Note that I do not use Flatpak.

This works with all my other applications: I am able to select and open files or directories when the file chooser is called by the application. This includes my web browsers, and therefore it works with Element web. This issue only happens with Element desktop, which leads me to believe that it comes from it.

Issue with Element desktop

Element desktop seems to support xdg-desktop-portal: trying to send a file brings up the file picker called through xdg-desktop-portal. However, Element desktop requests a directory instead of files.

I have reproduced this on two different computers with almost identical configurations.

Steps to reproduce

1. Install xdg-desktop-portal along with a backend.
2. Start its systemd service.
3. Set the environment variable GTK_USE_PORTAL=1 (possibly unnecessary).
4. Start Element Desktop.
5. In any room, click on the 'Attachement' button.

Outcome

Expected

The file chooser called by Element desktop should request one (possibly several) files.

What happened instead

The file chooser requests a directory. I can only select directories and, unsurprisingly, selecting a directory causes the action to fail. I am unable to send attachments with Element Desktop.

My thoughts

According the relevant documentation, it looks like the OpenFile method is called with the boolean option directory set to True.

This is confirmed by looking at the process spawning my file chooser: it passes the flags directory and multiple both set to True. The latter is expected (although not necessary); the former is the issue.
