The return type of `clone` should actually be `ThisType<this>` to better match what the JS is actually doing. This also makes it possible to override the clone method.

What does this expression do/mean?

IIUC, it's magic marker that changes how the this type is bound using the context it was declared instead of where it was called from. This is a workaround for some g3 conflicts, but I'm actually leaning towards abandoning this PR and asking that they don't try to override the clone method.

Seems a little magical but LGTM if it fixes the issue!
