// Selenium tests with InternetExplorerDriver fail if the zoom level is not set to 100% due to the fact that coordinates determined aren't correct.
// With this we enforce a zoom level of 100% before running a test.
// To make this work correctly you also need to set InternetExplorerDriver.IGNORE_ZOOM_SETTING to true (this should be pre-configured in local-test-environment.xml when activating IE driver)
