Fixes Overlay-Next selection when multiple objects are hit.
To reproduce:
- enable "Ovlay Next" in Preferences>Experimental
- create any Empty object and duplicate it without moving
- try to select by clicking them
Crash occurs because `mixed_bones_object_selectbuffer` in `view3d_select.cc` expects that `view3d_opengl_select_ex` will append results to `buffer`. Depending on situation after several `view3d_opengl_select_ex`calls with decreasing radius it tries to `slice` results from buffer:
```c
has_bones9 = selectbuffer_has_bones(storage.as_span().slice(ofs, hits9));
```
