### Problem description

[visibility.webm](https://github.com/user-attachments/assets/f2de43c9-bdcd-494b-a692-0d4323bc4c73)

Changing the visibility of the Body (with _Space_ or the visibility icon) causes the visibility icon of the Link to briefly show that it is invisible.

This does not seem to cause any issues but might cause unnecessary updates/recomputes.
I don't think its a problem with the icon but the Visibility property, the icon just makes is visible.
