Modal not opening correctly in phone-view

**Steps to reproduce the behavior:**
Open lightbox (modal) on an apple iPhone.

**Expected behavior:**
Not to stop and not require interaction for modal to appear correctly

**Actual behavior:**
Modals doesn't open automatically when using it with a mobile device,
instead, all images are lined up next to each other and the correct view only shows up when you actually press it again. It looks really weird and something is probably wrong.
