Error editing block property containing nested block property using on-page editing

Vote:
 

Hi,

We have a page (StartPage) which has a block property (FeatureBlock), which in turn contains another block property (ImageBlock). Editing any property inside FeatureBlock using on-page editing on StartPage results in a serialization-error. The payload (propertyName=feature&propertyValue={"imageBlock":{"image":"21681","altText":"Alt tekst"},"title":"Title","ingress":"","buttonText":"","buttonUrl":null}&id=6_25091&renderSettings={"BackgroundClass":"feature-box-block--with-bg"}) seems well formed when posted to /EPiServer/CMS/PropertyRender/Render, but the property value for the ImageBlock ends up as a string which cannot be deserialized. The issue is not present when editing in all properties view. I'm also not sure when this issue first occured.

Could not save property, and it has been reverted. Please try again.

I realize the issue could likely be worked around by using ContentReference properties instead of using the actual block itself, but this is a big project with many editors already used to the existing workflow, and many existing properties would lose existing data with such a change.
