I have a class shown below. When I run the build task, during the compileCommonMainKotlinMetadata task I get these errors:

Class 'FrameData' is not abstract and does not implement abstract base class member 'get'.
Class 'FrameData.FrameDataSegment' is not abstract and does not implement abstract base class member 'get'.

Which doesn't really make sense, because they do get implemented in my actual declarations. Even the test tasks work, and theres no warnings or errors in the IDE. Is this a bug?

public expect class FrameData : AbstractList<FrameData.FrameDataSegment> {
    /**
     * A single plane of the frame, represented as a list of bytes.
     */
    public inner class FrameDataSegment : AbstractList<UByte> {
        public operator fun set(index: Int, value: UByte)
    }
}
