Multiple Tabs can become .active at once

And this section:
JavaScript behavior
Use the tab JavaScript plugin—include it individually or through the compiled bootstrap.js file—to extend our navigational tabs and pills to create tabbable panes of local content, even via dropdown menus.
When you choose a dropdown item, and open the dropdown again and choose another item, both items are selected with class .active. It causes a bug, not being able to choose either of them again.
I think I fixed it here, I commented the lines with Fix 1 and Fix 2 so you can see the two modifications.
