Description Tyler Wilcock 2022-07-13 16:40:48 PDT

Informing some AX clients that they should suspend during rapid-but-short sync IPC calls can cause issues. An example where this is problematic is WebEditorClient::textWillBeDeletedInTextField() to InjectedBundlePageFormClient::shouldPerformActionInTextField, which results in a sync IPC call for every single deleted character.
