Attempting to update a collection's settings when there is an error, leads to no obvious indication without scrolling

Copied from bugzilla bug 1593229.

STR

Edit an existing collection's setup, by clicking the cog icon.
On a short-ish screen (so that the update button is off the page).
Do something to create an error, e.g. insert a comma to make a schema invalid.
Scroll down and click the "Update Collection" button

Expected Results

=> Indication there's an error, and what the issue is.

Actual Results

=> Nothing obvious happens.
=> Only when you scroll back up to the top of the page do you see the errors listed.

This appears to affect everything using our BaseForm component. Main plan is to create generic error handling there (assuming rjsf doesn't have something already) so we scroll to the top-most validation error when we fail validation.
