System Information
Operating system: macOS-13.0-arm64-arm-64bit 64 Bits
Graphics card: Apple M1 Pro Apple 4.1 Metal - 83

Blender Version
Broken version: 3.5.0 Alpha, branch: master, commit date: 2022-11-16 05:43, hash: c8c14d1681
Broken version: 3.3.1

Short description of error
If a .blend file contains a animation, and the animation is playing, and you're in the Cycles rendered viewport mode, then the viewport resolution/size will not update as you adjust it's size.

Exact steps for others to reproduce the error

Create a scene that has a colour that differs from the standard background colour of the 3D viewport.
Animate something in the scene (E.G. Animate the movement of an object)
Change the render engine to Cycles (This issue only appears in Cycles for me.)
Enter the rendered viewport mode so you're now seeing a Cycles viewport.
Start playing the animation.
While the animation is playing, start adjusting the size of the 3D viewport editor and notice how the Cycles rendered view isn't updating with the change in size. This is the issue. Once you stop playing the animation, it will update.

Here is a video demonstrating the issue:
