This contraption wasn't designed with that in mind, but it's an easy modification. The script for the "resize" button in the prototype:

on click do
 card.event["resize"]
end

Needs to call the prototype-level view[] event handler to reposition/resize the window title after user code has had a chance to run:

on click do
 card.event["resize"]
 view[]
end

The "close" button requires a similar tweak.

Here's a paste-able version with both modifications:
