--- Comment #10 from Oded Arbel <o...@geek.co.il> ---
I have the same issue with Slack - using "Open in desktop app" from the website
running under Chrome, results in kde5-open being called and mangling the
authority section of the URL.

I believe the correct RFC for QURL implementations - in this case - is RFC
3986: URI Generic Syntax, where section 3.2.2 says: "The host subcomponent is
case-insensitive". Granted that a reading of the spec to mean "fold everything
to lowercase" is reaching a bit, but as per RFC 1122, p1.2.2 - receivers should
accept lowercased host names.
According to discussions with Slack support, they are aware of this issue
-which depending on how you look at it, is either KDE doing unexpected things,
or Slack not complying with RFC 3986 - even though there's no way to know that
because they don't have a public bug tracker. The also suggested a workaround:
Apparently if you launch the `slack://...` URL from Firefox, it works fine: the
URL isn't mangled.
I'm not sure what Firefox uses instead of kde5-open, but looking at the code
for xdg-open, I can see that it has code to open flatpak apps that uses a dbus
call, and in that case no case folding is happening and the application is
launched successfully - event if the app is not a flatpak app. For example -
the following command launches the DEB installed Slack on my system:
gdbus call --session --dest org.freedesktop.portal.Desktop --object-path
/org/freedesktop/portal/desktop --method org.freedesktop.portal.OpenURI.OpenURI
""
"slack://MAGICTOKEN/magic-login/id-id-id-id-id-id-id-id-id-id-id-id-id-id-id-id-id-id-id-id"
{}
This call is handled by the xdg-desktop-portal process. Also, it may only work
because Firefox is running in a snap?
