- Fix crash when enabling the WebBrowser plugin on macOS. CEF uses a dylib scoped function pointer table for its API, so we need to enable it in the WebBrowser module, doing it in the CEF3Utils module doesn't help here. #jira UE-113510 #lockdown simon.tourangeau #ROBOMERGE-SOURCE: CL 16031887 in //UE5/Release-5.0-EarlyAccess/... #ROBOMERGE-BOT: STARSHIP (Release-5.0-EarlyAccess -> Main) (v789-15992632) [CL 16031906 by alfred reynolds in ue5-main branch]
