This was a compile error now thanks to microsoft/TypeScript#16047.
When a class implements an interface it normally has to redeclare all of the interface's members. (We weren't catching that because all of the members of
Overlay
were optional, so a class could declare itself to implementOverlay
without actually implementing anything.)We can fix this problem by merging the class with an interface extending
Overlay
, so it gets all of the members ofOverlay
without having to redeclare them.
