Javascript Array.includes can return false when Array.indexOf doesn't return -1

It seems that Array.includes doesn't check equality like Array.indexOf.
Array.indexOf behaves as expected but includes doesn't:
[(Qt.point(0, 0)].includes(Qt.point(0, 0)) returns false

Note the second attachment and the differences when using object properties or local javascript variables as array elements.
Everyline line should return true.
