As stated in the report, works fine in the viewport playback but breaks when rendering the animation.

This is an unreported dependency cycle: the IK controller cannot depend on the IK chain bones for obvious reasons. The real bug here is that the cycle isn't reported.

Couldn't depsgraph complain about this then? @Sergey Sharybin (sergey)

This is very much the same as T63136.
Reportedly, such configurations worked in 2.79, but i didn't get to the root of why exactly it broke.

But indeed should either support things on the same level as before or properly report cycles.
