I just discovered that I need to pass :chained_replace_html to  
#have_rjs , like so:
response.should have_rjs(:chained_replace_html, :hide, 'map-filter- 
errors')

However, after googling around and looking through the source for  
#assert_select_rjs , I have no idea what :chained_replace_html does,  
nor why :hide is insufficient. Would someone mind enlightening me?

Thanks!
