While performance profiling my application i came across a thing in the destroy() method of menu.js.

1. .find( ".ui-menu" ).addBack() 
2.              .removeAttr( "role aria-labelledby aria-expanded aria-hidden aria-disabled " + "tabIndex" )             .removeUniqueId() 
3.             .show();      

I'm constantly adding / removing selectmenus in my application when pages change for example. The call to `show()` here takes lots of time in this case.

I removed in in my fork and i can't seem to see any difference beside the fact that it doesn't take half as much time as before.

However the test case in the grunt build for menu.js fails.

I was wondering if this call is only beeing made to make the test case working. Is there a deeper meaning of this call to 'show()' ?

If no could i possibly remove it and contribute it to the project?
