DCE with MPP not working as expected

First: The DCE works fine in normal JS projects - with the new plugin: org.jetbrains.kotlin.js:1.3.71"
It eliminates unused classes and even unused functions.

Unfortunately it does not work the same for multi platform dependencies.

I have an implementation dependency to a mpp project.
Unused classes are removed. But not unused functions in used classes.

Is there anything I can do to improve this?
