Cutting components leave holes after layers disabled

[masp]

I've actually noticed this bug for several years: if I create a surface inside a group, then cut a hole in that surface (inside the group) with a (cutting) component, and then put that component onto its own layer, and then finally turn off that layer, the component will disappear, but the hole that it cuts in the surface will remain. To get rid of the hole I have to select the surface inside the group. It's quite annoying, as I like to use component (on their own layers) to model potential locations for doors and windows, and use layers (via scenes) to switch between them. But as soon as I put the surface inside groups I get these annoying ghost holes left behind by each component that is no longer visible because its layer has been turned off.

Steps to reproduce:

1. create a surface
2. create a group containing that surface
3. click into that group
4. cut a hole in the surface with a component
5. assign the component to a new layer
6. leave the group
7. turn off the component's layer
8. observe an annoying hole where the component used to be.
9. click into the group again
10. observe that the hole has disappeared.

Note: this only happens when the surface being cut is within a group (or component) of its own.

I can reproduce this in both directions (hide and unhide), see this screencast and the attached example model...

I would call this an unexpected behavior too.

It's annoying but has been like that since I remember.

I've verified that this bug was not present in Sketchup Free 7.1.6859 . I think it may have been introduced in Sketchup Free 8 (but haven't verified that). It's certainly been around for several years, surprisingly.
