[OPEN] External Tool assignments set to open in a new tab block the "Find Rubric" button.


Engineers are currently investigating the issue.


When creating an external tool assignment that is set to open in a new tab, and then adding a rubric to it, there is an iframe overlapping the “Find Rubric” button which makes it unclickable for mouses.

Expected Behavior

Don’t obstruct the “Find Rubric” button.


No workaround exists at this time.

Steps to Reproduce

  1. Create an external tool assignment in Canvas.

  2. Set it to “Open in a New Tab”

  3. Click “+Rubric” and then note that you cannot select the “Find a Rubric” button.
