Ionic and worklight

I have an ionic app that I need to ‘wrap’ in a worklight app. So now I have my app rendering OK in a browser, but when it runs in iOS there is a (status bar sized) gap between the nav header and the title bar. Has anyone experienced anything like this and if so, can you suggest how to fix it? I think the worklight css is conflicting with the ionic css.

I have no experience with worklight unfortunately, but can you try to fix it with platform specific css ?
Something like

.platform-ios . bar-custom{
background: green;
