Webform Autocomplete does not validate against list of options

[mariacha]

Describe the bug
From Christian M in slack:

My assumption was that the autocomplete element on webform would restrict entries to one of the defined values. But it seems that it will let people submit anything (at least on the webinar webform). Any way to trigger a validation error if it isn't one of the values? Or do we have to switch to dropdown.

Response: It does seem like a webform bug. I opened an issue and submitted a patch:

This can be QAed on https://develop-wriflagship.pantheonsite.io/events/2024/8/test-zoom-event

The user can submit an empty value for the Country, or choose an autocomplete version, or type in the exact text of a country's name and all should work. But if they try to type in something else, it fails.

Looks good to me @mariacha
