1.9.8: No new folders in Folder panel

[moropus]

XnView: MP 1.9.8 64 bit
OS: Windows 10 64bit

New folders in Folder panel in Browser do not appear if created from the top menu or shortcut.

To reproduce:
1. Open Browser, open Folder panel
2. Open context menu for some folder, click New Folder
3. Notice that new folder appears instantly
4. Click Menu Edit -> New Folder
5. OR press F7

Actual behaviour (bug):
- New folder does not appear in Folder panel as a child of current folder
- I need to hit Refresh to view new folders

Expected behaviour:
- New folder appears instantly in rename state

"Edit -> New Folder" create a folder in thumbnails view, do you filter the filelist?

I don't filter the filelist, but I checked the option in settings to hide folders.
