Graphics card: NVIDIA GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.59

Blender Version
Broken: version: 3.3.0 Beta, branch: master, commit date: 2022-08-22 16:15, hash: 4fecf652e2
Worked: 3.2

Regression from f4d7ea2cf6

Short description of error

In blender 3.3 beta, Incoming Vector in world shader is inverted in Eevee.
Below images show render preview when incoming vector is connectred to background nodes,
Eevee and Cycles result in different way.
(Default cube is also shown, where emission node is connected to incoming vector)

It looks that incoming vector is inverted in world shader in Eevee.
I found that in blender 3.2, the render results are the same for eevee and cycles.
(Same to that for cycles in 3.3 beta)

Exact steps for others to reproduce the error

Connect Incoming vector to Background node in world shader.
For comparison, edit material of default cube. Connect Incoming vector to Emission node.
Compare rendering results for Eevee and Cycles.

I uploded .blend file below.

Incoming.blend

(Also, I noticed that Normal and True Normal Vector in world shader in Eevee is also inverted.)
