Why Does the Compiler Allow Static Properties in Actors Without await?

...compiles and runs without warnings, but does not deterministically print 1000 like one would expect. This seems to me like unsafe, undefined behavior and a bug.

And to add to this, all it takes is changing actor MyActor to class MyActor to get the compiler to diagnose it (with -swift-version 6). Since static data is really just global data, it should be diagnosed the same way whether it's on an actor or some other type.
