Feature detection isn't working properly, at least for Chrome

[jason0x43]

In Intern 5-pre, Webdriver feature detection isn't working properly, at least not for all features. When functional tests are run in Chrome and feature detection is enabled, it will cause some Chrome functional tests to fail that do not fail when no-detect mode is used. Improperly detected features include usesWebdriverTimeouts and brokenWindowMaximize.
