After some more tests, it seems to happen when a layer is first removed.
To reproduce :
* start from a blank project,
* add a new layer,
* add another layer,
* remove the newly added,
* add another layer => it will be placed at the bottom, and if you do it
again, on top, and then at the bottom, etc.

Say, from a Python plugin, if you want to reorder layers rendered on the
map canvas. But what I observed might be linked to the previous issue.
