Do I understand correctly that in Babel class inheritance breaks the function name for IE?

Question

JavaScript

Babel implements the name property of IE functions using the babel-plugin-transform-es2015-function-name plugin. The problem arises when classes are inherited. If the code first asks for the name of the parent class, then the name of the child class turns out to be exactly the same, which, of course, is wrong.
Do I understand correctly that this is a Babel plugin bug?
