Conflict when upgrading webform module to be Drupal 10 compatible

I added the specific webform requirement to make sure that we check if any render element keys as defined in the WebformSimplifyElement plugins changed in between versions. Ideally, before expanding the webform version requirement, we would add some integration tests that make sure that all keys returned in the getFeaturePropertyMap method (like e.g. properties.form.length_container.minlength) actually exist in the relevant webform render arrays.

Please review.

Like I said, we're going to need tests before widening the version constraint. Also, a patch was already attached with the exact same change. I'm removing credit for now.

Feel free to re-open if I'm wrong, but I don't think this is an issue anymore. We're using this module om Drupal 10 and everything is working fine. I also don't see why we would need to drop Webform 6.1 support as long as we're supporting Drupal 9.
