Multiple [HMR] Waiting for update signal from WDS... after reload before it settles. #10633

Open LukaszGrela opened 3 years ago

I'm not sure if it is me or a bug, but during development when I need to refresh the page then multiple [HMR] Waiting for update signal from WDS... messages along other logs like the app would reload itself many times before it settles.

Is it normal behaviour, or my fault here?

Adding the console.log to the index.tsx main entry point file, it shows that it is reloaded many times, what could trigger this reload in HMR?

It is somehow connected to the OIDC UserManager When fresh user is logged in all is good, but when the user (not expired) is old e.g. a day then reload is causing this multiple HMR content reloads.
