"Find references" on methods acts as a toggle after not selecting from the popup (very minor)

[mzimmerm]

Steps to reproduce

Navigate to Browsing>>ClassPresenter

Click the "find references" button on #acceptResponse
Actual = Expected: Popup shows with method name acceptResponse and other messages named inside - this is correct
Click outside the popup
Click the "find references" button on #acceptResponse again
Expected: Popup shows with method name acceptResponse and other messages named inside
ACtual: Nothing happens
