+commit f457e3c32b8170a39ead84ceaf9f0fdbe0696649
+Author: Michael Lippautz <mlippautz@chromium.org>
+Date:   Tue Oct 15 19:27:32 2024 +0000
+
+    Fix size assertions across Blink
+    
+    The ASSERT_SIZE() macro is used to check that certain object sizes do
+    not grow unexpectedly. Fix a few occurrences that assumed that Member
+    is always the same size as debug builds may blow up the pointer size
+    to allow verifying some conditions.
+
