Space Group is not remembered

[e-kwsm]

Avogadro version: (please complete the following information from the About box):

• Avogadrolibs: 1.103.0
• Qt: 6.10.2

Desktop version: (please complete the following information):

• OS: EndeavourOS
• Compiler: GCC 15.2.1

Describe the bug

When an opened file is periodic but misses space group information (VASP, XYZ, etc), avogadro asks to select it. But it seems to be forgotten if other molecule is viewed.

To Reproduce

Fe (FCC)
 1.0
   2.94  0.00  0.00
   0.00  2.94  0.00
   0.00  0.00  2.94
   Fe
   2
Direct
   0.00  0.00  0.00
   0.50  0.50  0.50

1. Open the above POSCAR, select "Avogadro: POSCAR"
2. "Select Space Group" dialogue pops up, choose P1
3. Create a new molecule, or open another file
4. Switch back to Fe (FCC)—"Select Space Group" dialogue pops up again

Expected behavior

Once Space Group of a molecule is selected, remember it and the dialogue does not pop any longer.

That's weird because the Hall number should be stored in the Molecule object. I'll check it out.

Also I've been seeing the "select file type" dialog more, e.g. "Avogadro POSCAR" which shouldn't be happening. So two bugs in one.
