Labels are not shown in entire extent if map is rotated

We have a situation where a group of point features is oriented north-south and the map is rotated to fit in a narrow panorama-format layout.
Labels are only drawn in the central part of the map, not in the rightmost and leftmost parts.
I suspect that the extent for which labels are drawn is calculated before the rotation, so that anything that would not be visible in the map if no rotation was applied is not being labeled even if it is visible in the rotated map.
An example is attached - move the map extent to the left and right in print composer to see the effect (labels vanishing and reappearing near the borders).
Maybe this is somehow related to other issues with labelling and rotation (see ticket #12025).
