macOS: Search dialog in Help menu disappearing when editor active

[AlexisDrogoul]

Describe the bug
The search dialog in the Help menu disappears once an editor has been activated and doesn't come back after.

To Reproduce
Steps to reproduce the behavior:

1. Open GAMA
2. Check that the Help menu contains the search dialog

3. Make any view (except the editor) active
4. Make an editor active
5. Check that the Help menu has lost its dialog

Expected behavior
That the search dialog either is completely removed (little or no usefulness in GAMA) or remains in place.
