 in ClearableFileInput for this case?

 > Setting it both to `True` or `False` explicitly in the `attrs` does not
 trigger the `VariableDoesNotExist` exception to be logged. Only the
 absence of the `disabled` attribute on the `attrs` altogether triggers it.


 This error already handled in Exception when we do not provide "disabled"
 in attrs.


 {{{
 raise VariableDoesNotExist("Failed lookup for key "
                            "[%s] in %r",
                             (bit, current))  # missing attribute
 }}}

 {{{
         except Exception as e:
             template_name = getattr(context, 'template_name', None) or
 'unknown'
             logger.debug(
                 "Exception while resolving variable '%s' in template
 '%s'.",
                 bit,
                 template_name,
                 exc_info=True,
             )
 }}}
