Due to MediaWiki and our current design, around 35% of the initial view of a result set is global header stuff, "Search Media", search input, and filters. This isn't a huge deal in general since we know our users will scroll but it does become a problem with quick view and being able to see what is going on and some weird scroll behavior.
Our friends at Google Images get around this by auto scrolling down to the result set anytime you click on a result while the space above is still showing.
The file is too large to attach here, but here is a video of our experience and how Google handles it: https://drive.google.com/file/d/1V0jmxZAmxWrxhhPxUN6n7VXF0KYpThS7/view?usp=sharing
I think a similar scroll down could be beneficial into making our quick view be a bit more usable and useful.
