Mocks the "Building Will" dialog content (the result rows are built exactly as
the real dialog builds them) and shows the proposed bottom "Close" button that
replaces the "Please wait 5secs" auto-closing countdown.

BEFORE: last line is the countdown "Please wait 5secs" (dialog auto-closes).
AFTER : a real "Close" button at the bottom; the user closes when ready.
