JAWS - Autocomplete should announce invalid input when blurring

[DaveBest99]

Bug, feature request, or proposal:

Bug: AutoComplete has no error detection.

What is the expected behavior?

Moving focus out of an empty auto complete field where a value is required should either invoke an error or if a default value was initially assigned, reset the value to the default value. Also, moving focus out of an auto complete field that does not contain a valid entry should either invoke an error or if a default value was initially assigned, reset the value to the default value.

What is the current behavior?

Currently there is no error detection and anything can be typed into the Edit box.

What is the use-case or motivation for changing an existing behavior?

Help users (particularly elderly, screen reader and cognitive users) with accurate input.

Is there anything else we should know?

The user can press Enter key to select a blank Edit box or an invalid entry "Ontario", with no notification. An aria-alert could be used to notify the user that the selected list entry is not valid.

@kara I'm curious if there's an update on this? We disable/enable submit buttons in our application based on the status of required fields, so this is a bit of an issue and inconsistency from other material form controls. Thanks!
