Created attachment 153688 [details]
Reproduce when erase something

The thumbnail now does not change its boundary when erase, but still take those transparent pixel made by eraser into account, so the preview distort.

This happened after 5.2.0-prealpha-55b758bc2f (Windows) and 5.2.0-prealpha-ebe496e16f (Appimage) nightly build
Seems after the patch in bug 459273

STEPS TO REPRODUCE
1. Create a document, on the transparent layer, draw a circle on the left
2. switch to eraser, erase on the right side of canvas
3. thumbnail distort, pushing to left
