We inconsistently check for nullptr, which telemetry shows is triggering some crashes. This patch provides more rigorous checks for nullptr to avoid these crashes. 1961920 1 bfulgham 2023-06-15 15:38:01 -0700 <rdar://106964279> 1961930 2 bfulgham 2023-06-15 15:50:21 -0700 Pull request: https://github.com/WebKit/WebKit/pull/15025 1962178 3 ews-feeder 2023-06-16 16:22:18 -0700 Committed 265259@main (9632def06c0f): <https://commits.webkit.org/265259@main> Reviewed commits have been landed.
