1.11.5: File sort is not saved in Join images

[yudhi717]

XnView: MP 1.11.5 - 64-bit
OS: Windows 11 - 64-bit

After updating from 1.11.2 to 1.11.5
Files sorting is not saved in the join images
the sort header is saved but the image list is not sorted when join dialog opened

To reproduce:
1. Select some image.
2. Select Create -> Join images.
3. Change the file sort, e.g by Name Desc
4. Click OK or Cancel.
5. Select some images again
6. The file sort header is saved correctly but the file list / thumbnail is not sorted

Actual behaviour (bug): join images file list / thumbnail is not sorted

Expected behaviour: file list / thumbnail should be sorted with previous setting.
