* Fixed data dependency so that it builds necessary pak files.
* Quirks manager isn't available in this test.
* Do not run tasks in NetworkStateTestHelper setup, as it can run
  the tasks that should be run after setup.
* Set the host window bounds in AshContentTest::SetUp before
  initializing ash. AshTestHelper will set its own otherwise.
* Compute the test window size based on the display size.
  The current code uses fixed size and smaller than one used in
  interactive_ui_tests.
