1.8.0: In the gallery, after double-clicking to open a video, it cannot be deleted

XnView MP 1.8.0 - 64 bit
Windows 10

In the gallery, there are now some files. After double clicking to open a video, this video plays full screen.

In full screen, double click again, at which point it goes back to the gallery window.

But now the video cannot be deleted.

It appears to have a file occupancy problem.

The only way to release occupation is to close XnView MP or double click to open another video.

the video file is not opened in viewer tab?

I've just taken three screenshots, and below are the specific operations for reproducing the bug.

1. Open a folder and click on a video.

2. Double click to open it.

3. Double-click again to go back to the folder and try to delete it.

After that, an error will be reported, saying that the file cannot be deleted because it has been opened in Xnview MP.

show tabs, the viewer tab is always opened with video file so you can't delete it in browser
