### Description

I am migrating from Gatsby to Docusaurus 3 (I am running rc-1). I am seeing distortion in images. The example shown in the links below is added to the doc with ``

Images are distorted, stretched vertically.

I am running a basic Docusaurus v3 install (rc 1 from yesterday), I did not add change any settings, just enabled i18n, versioning, and auto-collapse on sidebar categories.

[example in Docusaurus v3 (1/3 down the page)](https://docs-stage.starrocks.io/docs/2.5/using_starrocks/Using_bitmap/)

### Reproducible demo

git@github.com:DanRoscigno/docusaurus-image-stretch.git

### Steps to reproduce

I can't reproduce this in a small site. My docs have 7,000 pages, and I suspect that this may have something to do with it. I am going to try some experiments (only build one locale, and if necessary only one version in one locale) to see if I can see when the images get distorted.

I will add a comment when I try the above experiment.

1. clone the above repo
2. yarn install
3. yarn build
4. yarn serve
5. open http://localhost:3001/docs/tutorial-basics/create-a-document

### Expected behavior

I would like the images to appear as if width and height were not set, removing these from the generated HTML gives the proper dimensions.

### Actual behavior

The same image when added to a small site looks great, but in my 7,000 page site the height is stretched.

### Your environment

- Builds were tested in GitHub actions and on macOS 14 (arm). On macOS I have started running the builds in Docker so that I can reduce the number of cores as I run out of heap if all 12 cores are used by node)
- latest Chrome and latest Firefox
- NODE_OPTIONS="--max-old-space-size=8192"

### Self-service

- [ ] I'd be willing to fix this bug myself.
