Environment
Kubuntu 24.04 LTS up to date : KDE Plasma 5.27.12, Qt Version 5.15.13.
Installed "oriongtk.earlybeta.1.flatpak"
Issue
When going to speedtest.net, I am getting spammed by pop-up windows with title "Select a Folder - Portal <#>". I've had 15 and 22 windows pop up and if I don't close them fast enough, Orion becomes completely unresponsive and I have to kill the process.
Steps to reproduce
Go to https://speedtest.net/ and wait a few seconds.

I have not clicked anywhere, or asked to load any file, so there shouldn't be a pop up asking for a folder.
Orion Beta linux, version 0.2.0, Kubuntu 24.04 LTS. No extensions installed.
EDIT: Multiple websites have the same behavior. I wanted to download an extension from Firefox (https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/) and I got the pop up once more when clicking on "Download file". No file was ever downloaded.
