Bad fonts in JOSM

[yoasif@…]

What steps will reproduce the problem?

1. Install JOSM from Flatpak on Fedora 37
2. Open JOSM

What is the expected result?

Ideally, I see the default fonts selected in my GNOME settings. Otherwise, I should see fonts that are not compressed looking.

What happens instead?

Really bad looking fonts.

Please provide any additional information below. Attach a screenshot if possible.
