Thanks for the report, I'm looking into this. Planning to fix this for next release.

This feature was not implemented in equirectangular and fisheye projections because I'm not sure how it should work, since in these modes there's no clear focus point. I think the most useful would be to keep things in focus in every direction around the camera, so basically instead of a "plane of focus" there is a "sphere of focus" that does not depend on the camera direction. Here's a few sample images:

Equirectangular:

Fisheye:

And no changes for the perspective projection.

Feature can be tested on the dev branch before release.
