+Subject: chore: add gin::wrappable wrapperinfo crash key
+
+This patch adds an additional crash key for gin::Wrappable, to help
+debug a crash that is occurring during garbage collection in SecondWeakCallback.
+
+The crash seems to be due to a class that is holding a reference to
+gin::Wrappable even after being deleted. This added crash key compares
+the soon-to-be-deleted WrapperInfo with known WrapperInfo components to
+help determine where the crash originated from.
+
+This patch should not be upstreamed, and can be removed in Electron 15 and
+beyond once we identify the cause of the crash.
