Research direction
Start with the 3v4l.org reproduction and compare the accepted {$foo::$Bar} form with the failing {$foo::Bar} and {$foo::class} forms. Trace the PHP interpreter's string interpolation and parsing entry points, then verify that both requested forms parse and produce the expected values without regressing the existing form.
