Symczyk, — U.S. -, 133 S.Ct. 1523, 1528, 185 L.Ed.2d 636 (2013)). Claims for damages are largely able to avoid mootness challenges. 13C Charles Alan Wright, Arthur R. Miller & Edward H. Cooper, Federal Practice and Procedure § 3553.3 (3d ed. 2017). Damages claims “are retrospective in nature— they compensate for past harm. By definition, then, such claims cannot be moot.” CMR D.N. Corp. v. City of Philadelphia, 703 F.3d 612, 622 (3d Cir. 2013) (internal quotation marks omitted). The Supreme Court has held that a damages claim is not rendered moot because a related injunc-tive-relief claim becomes moot. See Powell v. McCormack, 395 U.S. 486, 498, 89 S.Ct. 1944, 23 L.Ed.2d 491 (1969) (<HOLDING>); Bd. of Pardons v. Allen, 482 U.S. 369, 370
