EPUB: epub-title-page does not work from default file

[fsoedjede]

Explain the problem.

I have the following error while trying to use the new option epub-title-page implemented here: aaa3bea

Aeson exception:
Error in $: Unknown option "epub-title-page"

The markdown content to convert to EPUB:

---
# file: sample.md
title: Lorem Ipsum
lang: en
...

## Tempora pariter labore in mersa

Lorem markdownum et corpora tantis rictus dumque, partu agros lege equidem.

The minimal default file:

# file: defaults-test.yaml
epub-title-page: false

The command used:

docker run --rm --volume "$(pwd):/data" pandoc/core:3.1 sample.md --defaults=defaults-test.yaml --from=markdown --to=epub3 --output=expected.epub

If I use the following command passing directly the option in the cli, it's works without error.

docker run --rm --volume "$(pwd):/data" pandoc/core:3.1 sample.md --epub-title-page=false --from=markdown --to=epub3 --output=expected.epub

It tried to reproduce on try pandoc but could not.

Am I doing something wrong?

Pandoc version?
docker run --rm --volume "$(pwd):/data" pandoc/core:3.1 --version
3.1.1

We just forgot to implement this in defaults parsing.
Will fix!
