Subject: [PATCH] Bug fix for onload race condition

Proposed fix for bug illustrated on https://jsfiddle.net/olwimo/h633q2re/
Please note that this is a quick&dirty fix off the top of my head, and I haven't done any testing yet; I'll do a few quick tests soon, just to be sure I haven't missed some obvious fault/better solution, but I'm not too familiar with lightbox, so it's better if you guys find the "right" way to fix it anyway - I just didn't want to report the bug without at least suggesting a way to fix it.
