FWIW: When I first read this issue, I assumed it was similar to #7895 and that a fix like #8500 would be required. Is the current PR still allowing the default button on the page to be clicked and just stopping that from having an effect (versus avoiding the keypress from triggering the action at all)? Or are these not instances of the same base problem?

In this case according to Philipp, the preferred response to the enter key is to submit and save the group. In that other case since it was the whole dataset page, they wanted enter to be disabled.

I ran the code and it seems to do the job. Crazy that hitting enter was deleting groups!

A couple things I'll note:

• On develop (4e65f2f), in addition to the "Create Group" dialog I was also able to reproduce the "hit enter to delete" but in the "edit group" dialog. That is, got to "Group Members" and hit enter.
• Now hitting enter doesn't delete the group. Great! Perhaps it should trigger "Save Changes"? But this can wait for a future PR, I'd say.

The Jenkins tests were passing but I went ahead and refreshed from develop.
