“Cancel Edit” is a link that dismisses the modal. At first, I didn’t read it as a sentence and thought there was a cancel and an edit link weirdly next to each other. This would read more like a sentence if the E in Edit was lowercase. Our modals our inconsistent in the presentation and use of top left cancel.
Cancel Gallery shows a back arrow.
The media modal has a similar layout to Video details but doesn’t have a cancel link up top.
