Selenium WebDriver FindElement（noSuchElementId）抛出TimeoutException而不是NoSuchElementException

Question

IE 11和Selenium 2.37试图获取带有无效elementId的元素文本：

TimeSpan pageLoadTimeout = new TimeSpan(HOURS, MINUTES, m_WebPageSettings.PageLoadTimeoutSeconds);

InternetExplorerOptions IeOptions = new InternetExplorerOptions()
{
    InitialBrowserUrl = m_WebPageUrl,
    IntroduceInstabilityByIgnoringProtectedModeSettings = true,
    BrowserAttachTimeout = pageLoadTimeout,
    RequireWindowFocus = true,
    IgnoreZoomLevel = true
};

m_Driver = new InternetExplorerDriver(AppDomain.CurrentDomain.BaseDirectory, IeOptions);

m_Driver.Manage().Timeouts().SetPageLoadTimeout(pageLoadTimeout);
m_Driver.Manage().Timeouts().SetScriptTimeout(pageLoadTimeout);            
m_Driver.Manage().Timeouts().ImplicitlyWait(pageLoadTimeout);

result = m_Driver.FindElement(By.Id(elementId)).Text;

引发此异常：

OpenQA.Selenium.WebDriverException was caught
  HResult=-2146233088
  Message=The HTTP request to the remote WebDriver server for URL http://localhost:56732/session/4d8e064a-90b7-45f2-a7bc-42c7845534a4/element timed out after 60 seconds.

堆栈跟踪：

内部异常：

  InnerException: System.Net.WebException
       HResult=-2146233079
       Message=The operation has timed out
       Source=System

为什么它不会抛出OpenQA.Selenium.NoSuchElementException，我该怎么做呢？
