No Obsidian icon in window (tab) when installed with flatpak on Xubuntu

Steps to reproduce

On Xubuntu LTS 22.04 install the latest Obsidian version (v.1.1.9) using:

$ sudo flatpak install flathub md.obsidian.Obsidian

Log out & in, or even restart your machine.

The .desktop launcher shows the very cool Obsidian icon.

Expected result

When launching Obsidian, the window decoration and window desktop tab should show the Obsidian icon for easy retrieval.
This is especially useful when Alt+Tabbing between open applications.

Actual result

A generic window blue-white icon is shown instead.

Additional information

Other applications installed using flatpak do show their custom window icons on my system. E.g.: jabref.

we don’t make the flatpak. contact the author of the package.

OK, sorry. As the flatpak is advertised on, I mistakenly thought it originated from here.

Anyhow, I filed the bug report on GitHub with the flatpak packager.
