Summary:
NSTextField with allowsExpansionToolTips cumulate NSTrackingAreas

Steps to Reproduce:
We use a view-based NSTableView with NSTextFields, which are using allowsExpansionToolTips=YES.
And every time we add a subview somewhere else the NSTextField get another NSTrackingArea.

Expected Results:
We would expect that we have always one NSTrackingArea as maximum.

Actual Results:
We got a lot of NSTrackingAreas until the application is not useable any more.

The problem persists on Yosemite too.
