在全新的 Ruby 安装和全新的 webdriver 安装中，我无法使用等待或呈现？使用不存在的元素而不会导致非Watir Timeout 错误。

在下面的示例中，id 'gb_32' 在页面上，但被隐藏。ID 'gb_50000' 不存在。在这两种情况下“在场？” 应该返回 false，但第二个在 60 秒后给我一个超时错误。任何想法为什么会发生这种情况？

    irb(main):014:0> b.link(:id,'gb_32').present?
    => false
    irb(main):015:0> b.link(:id,'gb_50000').present?

I'd add this as a comment but evidently I can't yet. Are you using Firefox 17? Watir-webdriver isn't yet compatible with 17, so if you are then try reverting to Firefox 16 and see if your code works. I understand that a watir-webdriver update to resolve this compatibility issue is being released next week.
