1502307 - Marionette reports textfield in Shadow DOM not accessible

Status: RESOLVED DUPLICATE of bug 1503860

(Remote Protocol :: Marionette, defect, P3)

Description

[pascal]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:63.0) Gecko/20100101 Firefox/63.0

Steps to reproduce:

When trying to send text to a textfield embedded in a web component (shadow dom), the driver refuses with an org.openqa.selenium.ElementNotInteractableException, while in fact the element is interactable in the browser.
System

    Version: geckodriver 0.23
    Platform: macOS 10.12.6
    Firefox: 63.0
    Selenium: 3.14.0

# Testcase using Selenium/Java bindings and Geckodriver

WebDriver driver = new FirefoxDriver();
driver.get("https://pbi-qfs.github.io/selenium-demos/shadowdom/attachShadow_only.html");
Thread.sleep(1000); // just to be sure all js work in setting up the web components is done

// Access text field in shadow DOM
final WebElement element = (WebElement)((JavascriptExecutor)driver).executeScript("return document.getElementsByTagName(\"my-element\")[0].shadowRoot.getElementsByTagName(\"input\")[0]");

element.sendKeys("Text"); // Throws org.openqa.selenium.ElementNotInteractableException: Element <input id="shadow-text-inside" type="text"> is not reachable by keyboard

Shadow DOM support hasn't been added to the WebDriver spec yet. A first proposal is up on https://github.com/w3c/webdriver/pull/1320.

Duping to bug 1503860 because it has a better description.
