Is the ghusl for ihram sufficient for ghusl from masturbation for someone who was ignorant of its ruling and the obligation of ghusl from it before performing Umrah?

Ghusl (definition) (ritual bath) is obligatory after sexual intercourse, or the emission of semen with desire, by any means. Semen for a man is thick, white fluid, and for a woman, it is thin, yellow fluid. Masturbation necessitates Ghusl if semen is emitted. If a woman performs Ghusl after the emission of semen, or performs Ghusl after menstruation, which suffices for Janabah (definition) Ghusl, then her purification is valid. If she performed Ghusl only for Ihram (definition), some scholars are of the view that the Ghusl for Ihram is sufficient for Janabah Ghusl, especially in cases of forgetfulness or ignorance, and therefore, her 'Umrah (definition) is valid.
