Current Behavior

We are facing accessibility issues using the ComboBox control.
This control is not setting an aria-invalid attribute corresponding to the presence of an error message set via errorMessage.
You can check the render output and behavior here:
https://developer.microsoft.com/en-us/fluentui#/controls/web/combobox

If you check the same for a DropDown or TextField you can see, that these controls always set an aria-invalid attribute to either false or true:
https://developer.microsoft.com/en-us/fluentui#/controls/web/dropdown
https://developer.microsoft.com/en-us/fluentui#/controls/web/textfield

Expected Behavior

All controls should consistently use the combination of aria-describedby, role="alert" and aria-invalid in order to let screen readers correctly react to error situations.
For the ComboBox we built a workaround using autofill for setting aria-invalid at the inner input field depending on the presence of an error message for the time being.
