Is Younger v. Harris abstention appropriate when challenging the denial of Constitutional protections at prosecution; specifically when does prolonged deprivation of physical liberty through unconstitutional pretrial detainment constitute harm that is both great and immediate, sufficient to fall within the exception?

Whether the Ninth Circuit's decision in Arevalo v. Hennessy, 882 F.3d 763 (9th Cir. 2018), which held that the Younger abstention doctrine does not apply to a pretrial habeas petition challenging conditions of pretrial detention, conflicts with the Fourth Circuit's decision in this case
