Auto Refresh doen's't assume the group device selected

I wanted to correct an error that when Blazor itself refreshes the devices module, it does not take over the selected group of devices and ends up displaying other devices from other groups, where would this part be in the code, as I didn't find it?

Start by locating the Blazor devices module and its auto-refresh handling, then trace how the selected device group is stored and reapplied during refresh. Confirm the issue by selecting a group and observing whether the refreshed list shows devices from that group; done means the selection remains effective after Blazor refreshes the module.
