Bug: Unable to use 'pinch-to-zoom' while editing text

I’ve just encountered a bug, whereby I am unable to zoom in or out (using the ‘pinch-to-zoom’ feature, which is manually enabled in the Preferences of the app) while editing the text.

Email to support@omnigroup.com or omnigraffle@omnigroup.com - they’re not watching this forum (or at least they don’t take bug reports from it, is my understanding).
