Caused by 9676a1f61e

Short description of error
With Persistent Data Activated changing the light of any light object (Point, Sun, Spot, Area, even emission materials and world light) does not update in the render automatically. Tweaking some settings or deactivate and activate persistent data perform the update in light objects.

Exact steps for others to reproduce the error

In Cycles, activate persistent data.
Create a simple scene with a light object.
Set the light strength to 0. (alternatively: greater than 1)
Hit Render in a free slot.
Update the light strength to 1 or grater. (alternatively: 0)
Hit Render in another slot.
Compare. The light will not update.

Can confirm.

This is probably very much related with #87295 (Persistent Data ignores animation) (if not technically a duplicate).
Also caused by 9676a1f61e it seems.

Philipp Oeser changed title from ~~Cycles Persistent Data Light Objects do not update in render~~ to Persistent Data ignores light objects property changes
