`test\variable_scope_test.dart`: `variable scope variables in function` is failing

[bkonyi]

Failure log:

  Expected: contains all of [
              'aClass',
              'another',
              'intLocalInMain',
              'local',
              'localThatsNull',
              'nestedFunction',
              'parameter',
              'testClass'
            ]
    Actual: ['aClass', 'another', 'parameter']
     Which: has too few elements (3 < 8)

This test is currently skipped and should be re-enabled once DDC / DWDS resolves the issue.
