webviewer-ui issue reproduction

This is a minimal project to reproduce two issues with the WebViewer UI:

• Issue 1 #1101: Viewer crashes when it's resized to a narrow width, and the UI has some elements that are 'disabled' (via disableElements).
• Issue 2 #1102: Divider can not be enabled / disabled analog to other UI elements.
