I need to search for elements with specific class name within the Grid. I would like to leverage existing API and call something like gridElement.getShadowRoot().findElements(By.className(styleClass)), but that unfortunately fails with:

Caused by: java.lang.UnsupportedOperationException: getShadowRoot
	at org.openqa.selenium.WebElement.getShadowRoot(WebElement.java:280)

Since Grid does have a ShadowDOM, it would be good for GridElement.getShadowRoot() to work properly.
