Increases the zoom level.

The zoom level at which the browser control is currently displaying. Can be set to 0 to clear the zoom level (resets to default zoom level). NOTE: For browsers that share the same render process (same origin) this property is only updated when the browser changes its visible state.

You can isolate browser instances using a RequestContext, they will then have their own render process regardless of the process policy. You can manually get the Zoom level using GetZoomLevelAsync
