Worked: (optional)

Short description of error
Modify procedural does not update real time in view port shading in EEVEE

Exact steps for others to reproduce the error
Just a cookie with procedural noise in front of a point light in EEVEE (remove hdri if it's missing), I could not see changes while modify noise texture, also with viewer

Attached blend file and video

Can confirm that shadow maps are not updating unless you have Soft Shadows enabled.

I have simplified the file a bit [removed Add shader, deleted second light, turned off scene world, ...], to show this problem a bit easier:
(this file already has the Soft Shadows enabled, so updating the procedural noise will in fact update the shadow maps, but disabling Soft Shadows will not update shadow maps if you tweak the noise scale for example...)

studio-light-v1_phi.blend

@fclem: this can tbe on purpose, right?

This is not on purpose.

@Sergey it seems to me the object is not tagged properly but, it really is the material that is being change. Should the update tag go up to the object level?

This is what happens when I update the material if I run --debug-depsgraph:
