|--------------------------------------------------------------------------
| The manager loader must not outlive a download
|--------------------------------------------------------------------------
|
| The loader is switched on from beforeunload and switched off by the next page's load handler.
| A download never produces that load event - the browser sees Content-Disposition, cancels the
| navigation and leaves the current document in place - so the loader used to spin forever after
| "Download ZIP" in the file manager.
|
| main.js is a plain script rather than a module, so these assertions are made against its
| source, in the same style as the other manager script tests.
