=Acceptance Criteria [] Double check the following: Multiple bugs are happening when following the following steps. I didn't notice these bugs while doing a manual check as part of T145665#2675674, so I suppose the bugs were introduced recently, probably as part of a large refactoring we did in T147846. Browser: Chrome 53.0.2785.143 (64-bit) OS: Mac OS 10.11.6 (15G1004) 1. Visit http://reading-web-staging.wmflabs.org, login and opt-in for the Hovercards beta feature. 2. Go to http://reading-web-staging.wmflabs.org/wiki/Book and open the browser console. 3. Hover or the first link (“ink”) and quickly command click it (before a hover card shows up). Two bugs are happening here: * You’ll notice the error “VM1937:126 Uncaught TypeError: Cannot read property 'off' of null” in the console. * Both “opened in new tab” and “dwelled but abandoned” events are logged. 4. Another bug happens here: wait about 10 seconds and hover over the same link again and command click it after you see a hover card. You’ll notice that the 10 second wait is also included in the logged event even though you waited 10 seconds before hovering over the link. [] Create bugs for any encountered issues
