My Woothemes Canvas theme inhibits somehow the figure tag from displaying after upgrading to 1.5.0. Still not visible if I change the figure to picture, only if I change back to img and the data-media to src. The 1.4.0 version worked fine, so container, breakpoint settings remained as were. Jquery seems to be loaded, I added some css classes for figure.hammy-responsive. I changed the theme to Twenty Thirteen, that's how I now it should be Canvas' fault.
