"Fix: This is a fix for Clicking anywhere generates JS warnings in Firefox if a dropdown menu is present Issue #7318

Created by: shishirmk

When jQuery receives an empty id selector like this $("#") , it throws an error in firefox. This error is visible only in the web console provided by firefox. I was not able to see it in firebug console. I have just added a if statement as a workaround for it.

Here is the diff

This is my first pull request hope I have done it right
