After the PR which changes the
chart.options to a proxy, the usage of
Object methods (like
hasOwnProperty) are reporting only if the property are stored on top level.
Before the PR, the options, being built by merging the other options, the
Object methods worked well.
I don’t know if there is any possibility in order that proxy handler could work as before using the above methods, therefore going in cascade on the objects of different scopes.
