I'm trying to use the inspector, it works well until I try to inspect a specific view, at which point I always get: VM365:1 Uncaught SyntaxError: Unexpected token � in JSON at position 0 at JSON.parse (<anonymous>)...

The inspector goes blank and app falls back to the in-app inspector. The problematic view has some padding expressed as percentages:

        paddingTop: '20%',
        paddingLeft: '14%',
        paddingRight: '10%',

When I remove them, inspector doesn't crash, when I add them back, it crashes again the moment I select that view in inspector, so it's probably related.
