Meta -

OS: Windows 7 Selenium Version: 3.7.1 Browser: HtmlUnit Browser Version: 2.28.2

Expected Behavior -

when wrapping an HtmlUnitDriver inside an EventFiringWebDriver, advanced user interactions can be performed without exceptions

Actual Behavior -

an UnsupportedOperationException is thrown every time

EventFiringWebDriver throws this Exception, because the HtmlUnitDriver does not implement the Interactive interface; the BuildAction only catches UnsupportedCommandExceptions and therefore doesn't use the fallback option => is this meant to work this way and how do I cope with this?

Steps to reproduce -

• wrapping an HtmlUnitDriver inside an EventFiringWebDriver
• performing advanced user interactions

HtmlUnitDriver htmlUnitDriver = new HtmlUnitDriver();
WebDriver driver = new EventFiringWebDriver(htmlUnitDriver);

Actions builder = new Actions(driver);
builder.doubleClick().perform();

Yes, HtmlUnitDriver should implement Interactive interface.
