[🐛 Bug]: Invalid locator - GetShadowRoot and By.Xpath

[jrod567]

What happened?

When working with the shadowdom, using the By.XPath locator strategy is throwing an invalid locator unexpectedly.

Using other locators works fine and this is only an issue when working with IWebElement.GetShadowRoot() searchcontext.

How can we reproduce the issue?

IWebElement host = _driver.JH_FindElement(By.CssSelector("div[id='someid']"));
ISearchContext shadowRoot = host.GetShadowRoot();
IReadOnlyCollection<IWebElement> results = shadowRoot.FindElements(By.XPath(".//input"));

Relevant log output

Message: 
OpenQA.Selenium.WebDriverArgumentException : invalid argument: invalid locator
  (Session info: chrome=113.0.5672.127)

  Stack Trace: 
WebDriver.UnpackAndThrowOnError(Response errorResponse, String commandToExecute)
WebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
WebDriver.InternalExecute(String driverCommandToExecute, Dictionary`2 parameters)
ShadowRoot.FindElements(By by)

That error comes from Chrome directly, they need to support XPATH as well.

More context #11893. Please raise this with the Chrome/ChromeDriver team.

Depending on your situation you might try:

shadowRoot.FindElement(By.CssSelector("*")).FindElements(By.XPath(".//input"))
