To what extent must a claim be 'sufficiently foreshadowed in existing case law' for counsel's failure to raise that claim to constitute deficient performance under Strickland v. Washington?

Question Presented This case presents a question on which the circuit courts are split: to what extent must a claim to be “sufficiently foreshadowed in existing case law,” United States v. Morris, 917 F.3d 818, 823 (4th Cir. 2019), such that counsel’s failure to raise that claim constitutes deficient performance under Strickland v. Washington, 466 U.S. 668 (1984)? i
