`EditableDatumLabel` uses `activate`/`deactivate` methods for showing or hiding its widgets in the scene. However, `activate`/`deactivate` methods can end up being called as part of a scene graph / Coin action (`SoAction`) handler, in the context of `SoFCUnifiedSelection`, and this ended up in a Coin warning and eventual crash due to the scene graph being manipulated (nodes being removed), which Coin has checks for in debug mode: ``` Coin error in SoGroup::removeChild(): tried to remove non-existent child 0x5555579c5290 (Annotation) ``` Fix this issue by using a `SoSwitch` node instead and by controling the child visibility using it instead.
