Improve portability of fast/forms/listbox-selection.html

[Kent Tamura]

listbox-selection.html has potability problems:
  - it depends on Mac-specific metrics (itemHeight = 14)
  - it changes behavior by navigator.userAgent string

We should detect the item height at runtime like Bug#34072.
We should use "addSelectionKey" modifier for metaKey (Mac) or controlKey (others) like Bug#33989.

The change is basically good.  Thank you for taking this bug.

Did you confirm the change worked on Mac and Windows?

You had better add how to resolve the portability issue to ChangeLog.

The old expectation had information about what was tested, and new expectation has no such information.
An expectation files should have such information in order to detect what is wrong easily when a test fails. So, for example,

> +// 1) Select one item with mouse (no previous selection)
> +mouseDownOnSelect("sl1", 0);
> +shouldBe('selectionPattern("sl1")', '"10000"');

The first line should be:
  debug("1) Select one item with mouse (no previous selection)")

> +if (window.layoutTestController)
> +    layoutTestController.waitUntilDone();

> +if (window.layoutTestController)
> +    layoutTestController.notifyDone();

You don't need these blocks because js-test-pre.js and js-test-post.js are loaded.

Kent-san,

Thank you for your quick review! I really appreciate your kind suggestions. Your comments definitely help me because I am new to WebKit development. Unfortunately, I don't have a windows machine that can be used to test for now, so I'll send revised patch after I get a windows machine.

Thanks,

[Kenichi Ishibashi]

I've finally prepared a windows machine for the test and the test is successfully passed on the windows machine. I'm going to send a review request for revised patch soon.

Thanks,

[Kenichi Ishibashi]
