I think this is the expected result. When the menu is open google maps no longer prevent defaults the pinch gestures so we perform actual pinch zooming. Then clicking dismisses the menu and google then uses our pinch gestures to zoom the map and it does not affect the pinch zoom of the page, leaving the page in a pinch zoomed-in state. I get the same behaviour in Chrome.

I confirm that the same behaviour is in Chrome also. I'm going to close this bug.
Thanks.

Is there a way to recover from this situation, or do you effectively get stuck in the pinch zoomed-in state?

The only way I know to recover is to zoom out pinch zoom while over one of the "fixed position" elements on top of the map. You can't pan up or down because that is interpreted as zooming on the map by the site. It seems you can pan the visual viewport left and right. You can click the map to bring up a fixed position item with info about the location. Depending where you pinched zoomed you might be able to get out of the situation using that info.
