Invalid constant causes analysis server to stop updating problems view

[stereotype441]

Ran into this problem while coding the other day, and after some experimentation I was able to come up with a narrow repro.

Using VSCode, if I open an empty file and paste in these contents:

class Foo extends Bar {
  static const instance = Foo._();

  const Foo._() : super();
}

class Bar extends Baz {
  const Bar({required super.i});
}

class Baz {
  final int i;

  const Baz({required this.i});
}

No errors show in the problems view.

But if I analyze the same file using dart analyze on the command line, I see:

Analyzing foo.dart...                  0.8s

  error • foo.dart:2:27 • Const variables must be initialized with a constant value. Try changing the initializer to be a constant expression. • const_initialized_with_non_constant_value
  error • foo.dart:2:27 • Invalid constant value. • invalid_constant
           - The error is in the super constructor invocation of 'Bar', and occurs here at foo.dart:1:0.
           - The evaluated constructor 'Bar' is called by 'Foo._' and 'Foo._' is defined here at foo.dart:4:13.
  error • foo.dart:4:19 • The named parameter 'i' is required, but there's no corresponding argument. Try adding the required argument. • missing_required_argument

3 issues found.

If I add an obviously bogus line to the end of the file (like late static int class await(@String);, to name a random example I tried), there are still no errors in the problems view.

The problem seems to be related to the invalid constant declaration static const instance = Foo._();. If I comment it out, then the other errors in the file appear in the problems view. If I then un-comment it, the other errors in the file don't go away.

Reproduced using the latest SDK as of 54abf5e.
