After inserting site-id and page, it is possible to go back to site-id and change it. It can be changed to an invalid value, e.g. simply "a". When pressing the "save" button everything works, because "a" will change into the first value shown in the auto suggestion. When pressing enter, save will be triggered but JS will fail because the 'blur' event will not be triggered and also the new 'onkeydown' event used in I1e2b1272 won't be triggered (these would expand the "a" to the first suggested value from the list) probably because the 'onkeydown' event registered for saving the value is triggered first.
Simplest thing for now is to disable the site selection widget after selecting a site.
This issue does not occur anymore. Either it has been fixed by a patch not mentioned here or it was fixed due to refactoring which was going on over the year. I cannot reproduce this bug: when pressing "enter" the behavior is the same as clicking "save" and simply the first element from the suggestions will be selected.
