Following issue #22432 (closed) and PR #22433 , change the arrow color of popover when title is present -
See it in action here - http://jsbin.com/tubuwu/edit?html,output
Before
Arrow color was the same, regardless of the presence or absence of a title in the popover
After
Arrow color is now dependent on the presence or absence of a title in the popover
Technical
I've used an existing pseudo element of the title, originally intended to fix a gap between the popover and the arrow, and redesigned it to cover the arrow entirely with the title's background color.
