Vanilla 2

I have a dark themed site and I noticed that when using iframes they flash white. I have downloaded then uncompressed JS and included this within the iframe tag on line 90 in my version which only shows the iframe when fully loaded , so I dont get a flash of white

.......iframe style="visibility:hidden;" onload="this.style.visibility = \'visible\';" src ="{path}" width="{width}" .........

Though it might be something that could be included on the next release
