#1205 Toggle arrow when expanding fourniture group on list (🞂 ↔ 🞃)

[Pablo AB]

Right now with SH3Dv7.1 (installed through Flatpak) there is a small but annoying bug related to group of furniture, on the related list. The group is expanded correctly, but the arrow doesn't toggle as it should, pointing downward instead of to the left.

On other words, always stay 🞂, instead of toggling to 🞃 (U+1F783).
