Description

Hello,

using setDeferredToolTip causes a memory leak on browser side with Wt 3.5.0.

This can be reproduced quite easily with the attached source (a modified Wt example).

It uses a WTableView, where the delegate for a table cell calls setDeferredToolTip.

If you run the program and move the slider of the vertical scrollbar rapidly up and down,

you can watch the browser memory increasing quite fast e.g. in Windows task-manager.

The memory is not freeíd, if you manually trigger browser garbage collection within the development tools.

I have tested this with Chrome and Firefox.

Kind Regards

Looks like this is because we were connecting mouseenter, mousemove, and mouseleave using jQuery, which made jQuery.cache grow. I pushed a fix.
