`Trigger<Pointer<_>>` events are triggered for different position when using 2 cameras with `RenderLayers`

## Bevy version
`0.15.2`

## What you did

I am trying to render a scene and a **Overlay camera** (sort of like an UI camera but without `bevy_ui` elements).

## What went wrong
`Trigger>` Events are being triggered only at the cursor position of one of the cameras.

## Additional information
See my reproduction repo: https://github.com/michalvankodev/bevy_render_layer_bug/tree/main
