= Description
If you try to zoom in or out any image in the latest Wikipedia beta release, it doesn't work anymore (no reaction, it seems, that the pinch to zoom gesture is interpreted as a simple tap, as the caption of the image appears and disappears when you try to zoom). The same image(s) works without any problem in the stable version. The same problem can be reproduced in the alpha version.
