pressing SHIFT+ENTER in a form leads to submit the form what is not expected

[Christian Herzog]

We have a form for customers to create support tickets.
It contains a "Tenant URL" with field of type "URL", which is linked to Jira field "Tenant URL"
When the customer is in this field and presses SHIFT+ENTER, the form gets submitted without all the fields being filled out, which is not expected.
Can this be configured in order that pressing SHIFT+ENTER has no effect?
Or is it perhaps a bug?

Hi Christian,

Unless I am missing something, you should mark all fields as Required if you want them to have values in them before the form is submitted.

Yes thanks, we did this in the meantime.
The issue remains when all mandatory fields are filled.

Not a great answer, but you can add a mandatory tick box in the end that says something like "I agree that all the information I have provided can be submitted and processed." Since its mandatory it shouldn't submit until they've finished the form lol.

Thanks for your thoughts. 
Hmm, I'm not a friend of too much and unnecessary fields, this punishes all users.
Then is pressing SHIFT+ENTER the smaller evil.
