The issue is that we don't clear out a capture nested within a failed lookbehind. This actually is a long standing issue as we don't clear out nested captures within a failed lookahead. There is a long standing FIXME comment in the JIT code. I have a fix that I'll post soon. 1920931 6 msaboff 2022-12-20 15:57:41 -0800 Pull request: https://github.com/WebKit/WebKit/pull/7940 1921102 7 ews-feeder 2022-12-21 09:19:18 -0800 Committed 258195@main (6204c47b8556): <https://commits.webkit.org/258195@main> Reviewed commits have been landed.
