This re-introduced the ShortWaitForElement for the Use*Action, if the
|form_field_element| is specified. This is not a hard restriction, if
|skip_autofill| is true, the element does not need to be specified. If
it's not, the |RequiredFieldsFallbackHandler| will be called
immediately without waiting.
