From English Wikipedia:
'''Steps to reproduce:'''
- Edit the [[Vogrie House]] article in the visual editor.
- Resize the image. Larger or smaller doesn't matter.
- Press either CTRL + Z, or undo the edit using the undo button.
Instead of undoing the edit, it suddenly enlarges the image object. The image is placed in the center of the screen, and the object itself even overlaps the main navigation in the Mono interface. Of course as always: Firefox 22 used to test this.

I tried on Chrome on a Mac, and it didn't work there, either, but instead shoved the image to the left of the screen
