This does not have any effect at present because both of these bytes are only ever used *within* WebContent to up the hardening level, but it’s confusing / bug prone in the case that someone adds some condition that checks for those bytes elsewhere in the code. 2154686 1 marcus_plutowski 2025-10-28 05:33:53 -0700 <rdar://problem/163557770> 2154687 2 marcus_plutowski 2025-10-28 05:34:16 -0700 Pull request: https://github.com/WebKit/WebKit/pull/53080 2157316 3 ews-feeder 2025-11-07 12:31:20 -0800 Committed 302741@main (051e1cb9aeab): <https://commits.webkit.org/302741@main> Reviewed commits have been landed.
