Fussy mobile calendar in an AB container block

I’ve used the Atomic Blocks ‘Container’ block to get a wide calendar. The standard shortcode block doesn’t have a widealign option.
On mobile (an actual iPhone, not browser responsive mode [5s, 6s and Xr tested]), when the calendar is in this AB Container, the info bubbles don’t show when clicked. I *think* they’re off screen. If I take it out of the container, it works fine.
The first calendar on the linked page is *not* in a container, works fine, the second calendar is in the AB Container block.
