Floating view unexpectedly displayed in full screen

[xnvWolf]

XnView: MP 1.10.5 64 bit
OS: Linux Ubuntu 24.04 64 bit

In Tools/Settings/View/Fullscreen I set the following settings:
Show Toolbar: true
Floating views: false

When in fullscreen, the upper floating view is still displayed when moving the mouse to the top of the screen.
Moving the mouse to the right of the screen does not display a floating view.
When not showing the toolbar, all works fine.
However, when showing the toolbar, one need to be very careful to not move the mouse to far up, because otherwise the toolbar is hidden behind the floating thumbnails.

Please note: this is not related to XnView MP 1.10. This bug is around for quite some time (for me...).

Other settings of View/Fullscreen (just in case):
Auto zoom: Fit image to window, large only
Show playbar: false
Show info: true
Show scrollbars: false
Show toolbar: true
Hide mouse cursor: true
Background color: black
Dual monitor: Use second monitor: false
Floating views: false

To reproduce:
1. In Tools/Settings/View/Fullscreen I set the following settings:
- Show Toolbar: true
- Floating views: false
2. Enter full screen
3. Move mouse to the upper edge of the monitor

Actual behaviour (bug): The floating thumbnails bar is displayed
Expected behaviour: No floating view

Thanks for your great work, by the way.
