Touchscreens not working for menus

Something’s not working the way it seems like it should.

When I … try to click using a touch screen (both my computer and my smartboard) an item from a menu (e.g. three dots menu to Edit an Activity, or Switch Dashboards in the teacher dashboard menu)

I saw … nothing happens

But I expected … to go to the selected destination

Here’s the link to the page, dashboard, or activity: It’s no one activity, but only using Firefox. Chrome appears to work fine, though not my preferred browser.

And here are some screenshots or a video:
