Different behaviour of .dropup and .dropdown

[Neologist]

Referring to the docs (http://getbootstrap.com/components/#dropdowns) the only difference between the .dropdown and the .dropup class should be that one is opening downwards and the other one upwards.

In fact they behave different if you click inside them. The .dropdown will stay open and the .dropup will close immediately. If you just put an <ul> with links inside the container you won't notice this issue but if you work with other elements (e.g. a form inside of the container) it won't work because the dropup will close as soon as you want to fill a form field.

This presumably happens because

bootstrap/js/dropdown.js

Line 160 in 5c02844

.on('click.bs.dropdown.data-api', '.dropdown form', function (e) { e.stopPropagation() })

doesn't include .dropup

There are a couple additional instances of this in other plugins:

• bootstrap/js/scrollspy.js

  Line 119 in 5c02844

  .closest('li.dropdown')

• bootstrap/js/tab.js

  Line 95 in 5c02844

  .closest('li.dropdown')
