Printing: Cancel doesn't cancel

[mevans]

Print a ward directory.
Select what you want to show.
Choose Open PDF.
A new window opens where you'll see the PDF. In addition, a little dialog pops up at the top of the PDF Print Preview window that says "Generating PDF. This make take a minute.". In this window, there's the word "cancel" that you can click on.

I would expect that clicking on cancel stops generation of the PDF.

My experience is that clicking on cancel makes the PDF Print Preview window go away. However, the window in which the PDF is being generated does not go away and it continues to generate the PDF.

I checked production and get the same behavior, so this isn't new to the RC version.
