I totally understand you're thinking but I don't think there's a built in way of doing this. When you fire off the Alert component it has no knowledge of where it was fired off from. I guess you could look into Extending Alert to create your own MyAlert Class and override the show function (if possible) to allow another parameter to be passed in so MyAlert.show can receive an IUIComponent that is to get focus.
I've not looked into it but conceptually it should work but at some point you'd still need to set the focus, either in the alertHandler or perhaps inside the new MyAlert Class? Personally, I would create a global variable to store the temp reference to the object you want to refocus in the alertHandler().
