Do you know what's this log?

Question

i am developing spfx webpart. some sharepoint online page often prompts this kind of log:

Error: Error: Idle tracking cookie is missing.  
    at IdleSessionActivityMonitor.GetCookieValue (activitymonitor.js:365:23)  
    at IdleSessionActivityMonitor.InitializeSettingsFromCookie (activitymonitor.js:349:57)  
    at Function.LogIssoActivity (activitymonitor.js:130:26)  
    at HTMLDocument.IdleSessionActivityMonitor.HandleClick (activitymonitor.js:76:48)  

although this did not affect my page or webpart but it make me confused. If someone know something about this log. please kindly tell me

Hi @kong ,
Per my test, I can reproduce the issue and there seems won't affect the webpart work. After I doing some research, I found it's common in sharepoint modern site. I can even found the error in a new created modern page. So I think this is due to changes made by Microsoft.
