Issue description

The Canvas Layer does not update it's size after changing the Viewport Size in the Project Settings. To update the Canvas Layer size you need to uncheck visibility and check it again.

Steps to reproduce

Create a scene -> Add Canvas Layer -> Add any UI Element -> Change the viewport size

The Canvas Layer Size does not update accordingly. It needs to be manually updated by toggling the visibility. Edit: Resizing the Inspector Window or restarting the Project also updates the Canvas Layer

Can you still reproduce this in 4.0.3 and 4.1-beta3 or later?

[its-blue]

Yes, I could still reproduce this issue in Godot 4.0.3

Not reproducable in Godot v4.3.dev (f8a2a9193) - Windows 10.0.22621 - GLES3 (Compatibility) - NVIDIA GeForce RTX 3060 Ti (NVIDIA; 31.0.15.4601) - 12th Gen Intel(R) Core(TM) i7-12700F (20 Threads)

Can someone confirm this on 4.1.3 or 4.2.1? Otherwise this can be closed as fixed (otherwise the specific PR solving this should be identified and possibly cherry picked)

Tested on Windows 10 on 4.2.1; experienced inconsistent latency in a brand new project. It ranged from being instant, to taking 15 seconds, to taking an indefinite amount of time. Toggling visibility instantly changes canvas, as well as zooming in/out.

Reproducible on v4.3.beta.custom_build [93fc9b885] (on Windows 10). Note that the Canvas Layer updated after scrolling the mouse (the purple line moved), but children didn't update. After change the visibility, the child was resized.
