Issue: [Bug]: X/Y/Z grid adds progressively larger downward offset as z increases, resulting in bottom row cutoff
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

I generated a 27x4x15 x/y/z grid of 512x640 images in txt2img, with the attached x/y/z settings
![chrome_2023-03-02_08-47-44](https://user-images.githubusercontent.com/24497594/222496246-242fa0e1-43cb-43e0-a817-73d8ad03f88a.png)

Upon viewing the result, I noticed the bottom row becomes progressively more cut off as the actual image grid does not start until a progressively lower and lower point on the image. I've attached scaled jpeg since the original is a bit unwieldy.

Shown here is a reproduction interrupted early on for space and time purposes from latest commit

### Steps to reproduce the problem

Create a x/y/z grid of for instance 512x620 images, x containing a large number of entries may be important?   I reproed with 27x4x15, x addnet model 1, y addnet weight 1, z checkpoint name.

FWIW some of the checkpoint names in the z "axis" had long strings, and almost all the addnet strings in x were long

If you observe the result you find that with each z grid a noticable slight drop in starting position of images occurs

WebUI run through Chrome Version 110.0.5481.178 (Official Build) (64-bit)

### What should have happened?

all subgrids should be started at a fixed coordinate in the vertical direction
