windowLayout not honored

I'm passing in options for `windowLayout `and nothing seems to matter. The other options are loading but it seems to be ignoring my `windowLayout`.

I've tried just adding main, or adding `equalizer: {closed: true}`. But nothing seems to happen.

Start by reproducing the issue with the reported windowLayout options, then trace how windowLayout is passed through the TypeScript frontend and applied to the window arrangement. Done means values such as main and equalizer.closed visibly change the initial layout, with coverage for the supported options if an existing test location is found.
