CSS class selector 'view-main' not found

In F7 V6.0.1 I get a message ‘CSS class selector 'view-main' not found’ in my Visual Studio Code. I’m sure V5 didn’t have this problem. This is only a message within the dev environment though, it’s not an issue when compiled as a running Cordova project.

Am I right in thinking the view-main CSS class is dynamically created in script now? Or am I doing something wrong to see this error message all the time?

Not really, this class should be added to the main View
