Safari ignores browser size configuration

[elvijsTDL]

Setting browserSize or startMaximized to true does not change the Safari browser size during test runs.

Configuration.browser = "safari";
Configuration.automationType = Configuration.DESKTOP_PLATFORM;
Configuration.browserSize = "1920x1080";

Expected results:
Safari starts up and the browser size is 1920x1080

Actual results:
Safari starts up and the browser size is the default one
