a50cb89 wpt: run reference-named files which are themselves tests (#836) (2026-09-03)

Subtest	Status	Message
Number parsing: M 100-200 parses as M 100,-200	FAIL	not a callable function
Number parsing: First coordinate is 100, second is -200	FAIL	not a callable function
Number parsing: M 50+100 parses as M 50,+100	FAIL	not a callable function
Number parsing: M 10-20+30-40 parses as M 10,-20,30,-40 (implicit lineto)	FAIL	not a callable function
