           Summary: Web Automation: script evaluations via WebDriver
                    should have a user gesture indicator
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Some JS/DOM APIs only work require a user gesture indicator. Since there is no real user input when running via WebDriver, these APIs can only be tested if WebDriver code has a synthetic user gesture indicator, or explicit checks for a user gesture indicator should also allow usage iff page->isControlledByAutomation().

It would be nice to do the first approach since only one source location is needed. However, it's possible via WebDriver to evaluate "async" JavaScript which calls a completion handler some arbitrary amount of time later. The naive approach to set a user gesture indicator would only allow gesture-requiring API calls that happen synchronously.

So, we need to either set a user gesture indicator using non-RAII code, or audit every single check and add || page->isControlledByAutomation() to the condition.
