2. Select the 12x12 pixel blue square with the rectangular selection tool.
3. Layer -> Transform -> Rotate -> Rotate Layer 90° to the Right
4. Repeat step 3.

OBSERVED RESULT
The selection moves 1px upwards on each rotation until it stops at some point.

EXPECTED RESULT
Rotate the selection in-place without moving it.

Interestingly, it doesn't happen if you import this little picture onto a bigger picture, only when the canvas is very small.

But I can confirm it does happen if you just import that little picture using File -> New -> From Clipboard.
