Required `CursorIcon` component on different entity than Bevy

[djeedai]

See jakobhellermann/bevy-inspector-egui#295. bevy_egui forces the CursorIcon component on the entity with a Camera instead of the one with a Window like Bevy does. This causes issues with queries for CursorIcon as it seems this component is dynamically added and removed. Eventually some of my queries fail while bevy_inspector_egui says they should succeed, likely because of system ordering.

Hi! Thanks for the report. Yeah, EguiContext has CursorIcon component as a required one, and I believe it's not even used there. I've removed it in 25507d3, so this will be fixed in the next release (probably in the major one coming with Bevy 0.18).

The other thing worth noting though is that bevy_egui also updates CursorIcon of window entities (in process_output_system). If you want to disable that behaviour and manage CursorIcon on your own, you can set enable_cursor_icon_updates to false (see EguiGlobalSettings or EguiContextSettings).

Thanks for the details! I was mostly caught by my query failing while the inspector saying it should succeed. But it's easy to work around.
