Widevine CDM crash because of plugin-container.exe rules

[n-zhi]

Hi, after the Firefox update I got Widevine CDM crashed all the time I try to play DRM content in Firefox. I checked the rules and figured out that this is because of "EnableRopStackPivot" rule for plugin-container.exe So, the working config is: Set-ProcessMitigation -Name plugin-container.exe -Enable DEP,BottomUp,CFG,AuditRemoteImageLoads,AuditLowLabelImageLoads,EnableExportAddressFilter,EnableExportAddressFilterPlus,EnableImportAddressFilter,EnableRopCallerCheck,EnableRopSimExec,SEHOP,TerminateOnError,AuditChildProcess

Firefox 94.0.2 x64, Widevine CDM 4.10.2391.0, Windows 10 19043.1348
