Named class expression extending import-aliased class does not bundle correctly

[dmp-gottschalk]

Description

When extending a class, which was imported and aliased, in a class expression, using the same name, there will be a name clash after bundeling.
This will throw a ReferenceError: Cannot access 'ClassName' before initialization at runtime, every time the class expression gets executed.
