@LeafShi1 can your team take a look (not immediately urgent) to see what we're missing here in either the test app or the runtime to support the tabbing from control to control?

copy and paste now works in DemoConsole in netframework481 but not in net10. that's because the serializer here does not work in net10, it was deprecated long time ago.

In order to make it work, we need to find another way to serialize CodeDomSerializationStore
