* Passing test * Failing test * Fix test It still fails, but now fails correctly * Fix refreshing transcluded functions (#7755) We store the previous result of the filter function and recalculate it when the transclude widget needs to be refreshed, refreshing the widget if the result is different. --------- Co-authored-by: Jeremy Ruston <174761+Jermolene@users.noreply.github.com> Co-authored-by: Robin Munn <rmunn@pobox.com>
