Safari zooms the whole page when you pinch, and Idea Workspaces stopped that only over the canvas. A pinch that started on the tools beside the canvas or the zoom buttons enlarged the whole page instead; the canvas then filled the screen and took every pinch for itself, so the page could not be pinched back to its normal size. Pinching anywhere on an Idea Workspace now leaves the page as it is, and pinching the canvas zooms the canvas as before.
Pinching an Idea Workspace no longer enlarges the whole page
On an iPad, a pinch that started on the tools or the zoom buttons could enlarge the whole page, and the page could not be pinched back. It now leaves the page as it is.
