It does however work fine on IE and Edge, except for one of our sites using the PianoForte template.
As PianoForte didn't include the Gridgallery out of the box when purchased we used the following script inserted into the Template's "Head custom code" in order for the Gridgallery module to work properly.
<script src="//http://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.2/modernizr.js"></script>This doesn't seem to work any more. However it seems to work (when using IE or Edge) when the code is inserted directly into the index.php head which is a little weird.
I tried to look at your demo of the Habitat template which includes the J51 Gridgallery module, and it seems that the demo page has the same issue. URL to our site running PianoForte is provided.
