Galleries with less than one full row disappear on resize

I had the issue that galleries with less than one full row disappear when resizing the window. I looked at the JS code and the issue seems to be that resize_scale is set to previous_row_resize_scale. The latter is never initialized when row_is_full is never true.

I could solve the issue on my own page by adding the following code in line 177 of main.js: if (!resize_scale) resize_scale = 1;

It would be great if you could include this or a similar solution with the next update.
