<a> button :focus styles not overridden correctly.
Created by: LarryAzevedo
On any desktop browser, do the following:
- Go to http://v4-alpha.getbootstrap.com/components/popovers/#dismiss-on-next-click
- Click on the red Dismissible popover button to bring up the popover.
- Finally, move your cursor off of the button.
The text of the button changes to blue; which in my opinion, looks and feels a little weird.
