Partially written files sometimes prematurely have thumbnails generated

Created attachment 9484 Script for generating 100 images with random noise (to generate thumbnails for)
Sometimes, particularly when many files are saved quickly, having Thunar open in the same directory causes some thumbnails to be generated before the file is finished writing. This results in the thumbnail having a section of grey rows at the bottom. Refreshing or navigating away and back does not cause the thumbnails to be regenerated (for the changed, completely written file).
The issue is somewhat reproducible with the attached script, while having Thunar navigated to the same directory.
