Opened workflows not positioned properly

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What problem are you experiencing?

Whenever I open certain workflows, the canvas position is incorrect or effectively unusable, regardless of the state of the “**_Save and restore canvas position and zoom level in workflows_**” option, as shown below:

When this option is **disabled**, ComfyUI should automatically re-center the canvas to the actual center of the opened workflow — either at 100% zoom or using Fit View.

At the moment, this does not happen, which makes the saved/initial canvas position largely ineffective in these cases.

### When does this problem occur?

- When loading a workflow.

### How often do you encounter this problem?

Daily

### How much does this problem affect your workflow?

Causes moderate inconvenience

### Current workarounds

Click the Fit View button to center the canvas.
