==== What is the problem?
For some images, the height of the thumbnail generated by my local thumbor-plugins is different to that generated by beta.
For example:
* Beta (height: 225px): https://upload.wikimedia.beta.wmflabs.org/wikipedia/en/thumb/1/1b/CuteGoat.jpg/320px-CuteGoat.jpg
* Local (height: 224px): https://gitlab.wikimedia.org/dwalden/thumbor-testing/-/blob/main/data/local_320px-CuteGoat.jpg
==== Reproduction
My configuration (thumbor.conf) is: P34931
I generate the thumbnail on my local system by going to the url: `http://localhost:8800/thumbor/unsafe/<width>x/<url>`.
I have reproduced it with thumbor running in docker on Buster:
```
$ blubber .pipeline/blubber.yaml dev > Dockerfile
$ make build
```
I have also reproduced this when I installed locally via python on Bullseye:
```
python3 -m pip install -r requirements.txt
```
