What happened?

The By type has special handling in many cases for custom methods. We use it to make sure FindElements(By.Id("")) returns an empty list instead of throwing. Users can also override By.FindElementMethod and By.FindElementsMethod for custom implementations.

This has been applied to WebDriver and WebElement, but not to ShadowRoot. We can apply it there as well so By behaves consistently.

How can we reproduce the issue?

driver.Url = shadowRootPage;
IWebElement element = driver.FindElement(By.CssSelector("custom-checkbox-element"));
ISearchContext shadowRoot = element.GetShadowRoot();
Assert.That(shadowRoot.FindElements(By.Id("")), Is.Empty);
