Dashboard widget maximize (fullscreen) fails when dashboard has only one view

[anneb]

Describe the bug

When using dashboards in GeoNode (MapStore client), clicking the widget “maximize” (fullscreen) icon fails if the dashboard contains only one view.

Instead of showing the widget maximized, the dashboard content becomes blank (white container). No network requests or JavaScript exceptions are triggered.

If a second view is added (even an empty one), the maximize behavior works correctly.

Expected Behavior

When the maximize button is clicked, the widget should take up the full height and width of the dashboard container

Steps to Reproduce the Problem

1. Create a dashboard with at least one widget and only one view
2. Click the 'maximize' icon at the top-left of the widget
3. The view is empty (all widgets are removed from the DOM in the dev console element viewer)

workaround: before clicking 'maximize' add a second (empty) view => maximize works
