In master (`bcf9c73cbc8386bdef1e08af73e66d0e5c57ad6e`).
Open this file: {F10158879}, press Shift-Z. The file asserts with:
```
BLI_assert failed: source/blender/draw/intern/draw_cache_impl_mesh.c:1187, drw_mesh_batch_cache_check_available(), at '!DRW_ibo_requested(((GPUIndexBuf **)&cache->final.ibo)[i])'
```
I bisected this back to rBc65f4b3d76deb47017a2e661290481e5e613b5db.
