AssetManager, uploads and loading list of assets

[DewaldBodenstein]

I'm experiencing issues with the asset manager and uploading. The uploads definitely work for me and are added to the list (using {autoAdd : 0} and adding the image with AssetManager.add() function on the upload response event. But the AssetManager is only showing the asset that was added while it's modal is open. Close and re-open and its gone. Checking the assets array has all the assets that I've uploaded before that I've added to the assets list config option. This does not make sense at all! Can someone please shed some light on how this AssetManager works please.

Okay, I tried one last thing.
I figured it had something to do with the render function and filtering.
After adding a call to render() on the modal:open event, it is showing all assets:

editor.on('modal:open', () => { editor.AssetManager.render(); });

This is very confusing behaviour. Can someone please explain why it works this way.
