This is due to --sloppy-harmony. It is not clear what is going on here.

+PASS new (class extends null { constructor () { this; } }) threw exception ReferenceError: this is not defined.
+PASS new (class extends null { constructor () { super(); } }) threw exception TypeError: function () {} is not a constructor.
+PASS x = {}; new (class extends null { constructor () { return x } }) is x

Same test again... not sure why it is duplicated :-)

+PASS x = null; Object.getPrototypeOf((class extends x { }).prototype) is null
+PASS Object.prototype.isPrototypeOf(class { }) is true
+PASS Function.prototype.isPrototypeOf(class { }) is true
+PASS successfullyParsed is true
