[Bug]: (Dev Branch) Placing "Dimensions" first in "ui_reorder_list" prevents start

[Reibies]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What happened?

The current Dev Branch has a bug that causes it to not load when changing "txt2img/img2img UI item order".
It seems to only be when dimension is set to be first in the UI:

    "ui_reorder_list": [
        "dimensions",
        "cfg",
        "seed",
        "sampler",
        "checkboxes",
        "hires_fix",
        "batch",
        "scripts"
    ],

Steps to reproduce the problem

1. Change your UI order in settings under "txt2img/img2img UI item order" so "dimensions" is first
2. Save Settings
3. Reload UI or restart fully

What should have happened?

Should have been able to place "dimensions" at the top of the UI order even in dev branch.
