[5.x]: Image Editor has inconsistent horizontal and vertical flipping #18486
Description
What happened?
Tested on both the latest Firefox and Vivaldi, same results.
No errors in the browser’s console.
The image itself doesn’t seem to matter (picked several random ones).
Sometimes they flip, sometimes they don't.
