Thumbnails are displayed too small in HiDPI environments

Steps to reproduce

1. On any Desktop Environment that supports it set scaling to 200%
2. Add some pictures to any folder. For example Pictures
3. Add a new folder for icon size reference
4. Zoom to a higher than default zoom level for the difference to be more apparent
5. Wait for picture thumbnails to be generated

Current behavior

The displayed image thumbnails are too small (in comparison to the folder icon), i.e. they cover only 50% of the available space in 200% scaling.

Expected outcome

Even in HiDPI mode thumbnails should be displayed in consistent size with the rest of Thunar.

Backtrace

N/A

Additional information

This only happens in HiDPI mode. Setting scaling to 100% shows the correct sizing.

UI scale 200%:

UI scale 100% (same zoom level as above):

I don't fully understand the Thunar code base, but probably scale_factor should be used in Thumbnail display similar like for icons here: !327 (merged)

Version information

thunar --version
thunar 4.18.10 (Xfce 4.18)
