Steps to Reproduce: Visit Special:MediaSearch in iOS (confirmed that this is an issue in Safari, but it probably exists in other browsers too)
Actual Results: Select menu appears hidden behind other content
Expected Results: Select menu should be visible
This is caused by the CSS rule -webkit-overflow-scrolling: touch; on the parent container, which is intended to enable momentum-based scrolling horizontally for the filters, but is having the unintended consequence of hiding content on the y-axis as well.
