Steps to reproduce the issue:
# Create two panels dashboard, one public, the other accessible for all users
# Create a tabbed panel with the two precedents as content
# Add it to a dashboard, accessible to public
Expected behavior:
- At edit time, to be warned of the incoherent state of the widget editing
- At view time, tabs with non accessible content inside should be skipped
Current behavior:
- At edit time, no warning
- At view time, inaccessible tab is visible and when opened prints (Invalid Panel) and breaks the bottom of the panel end's design doing so.
