-Subject: fix: retain compatibility with MSVC++
-
-The C++ standard has always forbidden containers of const elements such
-as std::set<const T>.  In order to retain compability with MSVC++ this
-code can not exist in Chromium.
-
-This should probably also be fixed in libc++ to prevent this occurring
-again but this fixes the build for now.

+
+Electron ipc messages used to piggy back on ShellMsgStart for ipc
+identifier. But its not available after
+https://chromium-review.googlesource.com/c/chromium/src/+/1525181.
+This patch can be removed once legacy ipc messages are no longer
+used.
