Replace info.This() with info.Holder()
If the object is not window, info.This() == info.Holder(). Hence, we can just replace
info.This() with info.Holder().
If the object is window, info.Holder() is the inner window and info.This() is the outer window.
However, all accesses to the outer window are redirected to the inner window.
Hence, the replacement doesn't change any behavior.
