Flatpak: g_app_info_launch_default_for_uri() silently fails for in-sandbox host files
After attaching a file (such as a PDF, JPEG, or PNG) to an email message, Evolution does not allow for previewing the file when it is in a Flatpak.
It's useful thing to do, letting you know that you're sending the correct file.
I expected it to open the file via a portal, similar to viewing an attachment on a received email.
Previewing attachments was solved for received messages in #169 (closed). This might have a similar fix.
This is on Evolution on:
- Fedora 33
- 3.38.1 (by Flathub.org)
- on Wayland
