Crash log

Chrome for iOS is getting reports of a high-volume crash in IPC::Connection::dispatchToClient, on iOS 18.0 and 18.1 beta.

We don't have steps to reproduce, but top crashing URL by far is https://kip-kuliah.kemdikbud.go.id/siswa/auth/login

Is this the bug fixed by https://bugs.webkit.org/show_bug.cgi?id=279188?

I've attached a crash log.
