[Dropdown] Fix IE11 dropdown re-focus issue

[andrei-piatrou]

@jokeronaldo Here is JSFiddle.

1. Please, use IE11 to reproduce the bug.
2. Click on user icon and choose Settings for example.

Actual result: dropdown will be closed and immediately opened.
Expected result: dropdown is closing and will not be opened as it is in other browsers.

I was able to reproduce.

This is caused by using anchor links that point to the same href, as a blank link like href="#" does.

I'd recommend not using a blank href link. I can't preventDefault here because people can use href to link out. I can confirm using an external link wont cause it to re-open before pageload. So this is only a case with anchor tag in page links.

@jlukic JS fiddle is just a sample how to reproduce. I have the same behavior when use regular links in a EmberJS SPA (Single Page Application).
