Improve machine name AJAX focus handling integration

Posted MR which should fix the bug. I spend some time trying to write tests for this but it seemed tricky to reproduce this in tests because it requires triggering the tab key press and change event at the same time.

Did manual testing of this issue.

Adding a List(text) field to a content type and purely using my keyboard, saw the issue you're talking about where after I input a label and tab focus comes back. The MR corrects this issue.

As far as a test goes. Could it be as simple as press tab key and just check where the focus is? For me the ajax didn't seem to run till after I pressed tab so doesn't that mean the event triggers automatically with the key?

This is really tricky to test because I couldn't figure out a way to change the field value using Mink without immediately triggering the change event. I tried some approaches with JavaScript but couldn't get the right sequence of events triggered. I think we should consider committing this without tests given that this is pretty challenging to test using our testing system.

Thanks for taking a look! In that case RTBC+1

Confirmed the bug and fix with similar manual testing. Agree that test coverage is trickier than it's worth to write.

Committed and pushed 874adf1734 to 11.x and 27d9ff8359 to 10.2.x. Thanks!
