I report this bug analogous to the bug
The “zoom” function also only works in edit mode.
The arguments for having zoom work in navigation mode are the same, but here even stronger.
Firstly, “zoom” is undoubtedly not an edit function and secondly, zoom can already be activated in navigation mode via the mouse (click on the bullet points).
So I assume this is not intentional. Having zoom also in navigation mode would be another step towards reducing the barriers between the two modes.
