Possible fix for #6448 and #6487.

By doing this are we not wiping away ay errors that need actions from users?

I also don't see how this fixes the errors referenced in the PR post; it seems to me we should be more lenient in how we tolerate post-device-wake-up errors in the client, rather than changing how errors are presented

Yes, I am still thinking on how to properly/correctly approach this.
