Somehow, the test for webInspector.inspectedPage.reload() added in Bug 51485 wasn't landed. This lead to webInspector.inspectedPage.reload() being eventaully broken by a change in inspector backend interface (PageAgent.setUserAgentOverride() -> NetworkAgent.setUserAgentOverride()).
Created attachment 102533 [details] patch - Fixed webInspector.inspectedPage.reload() - Broguht back tests for the above - Removed redundant user-agent override from FrameLoader::loadResourceSynchronously(), this should happen indirectly via a call to addExtraFieldsToSubresourceRequest()
