Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has acontribution guide which I suggest you to read.

In short:

• Always add tests
• Keep backward compatibility (seehttps://symfony.com/bc).
• Bug fixes must be submitted against the lowest maintained branch where they apply (seehttps://symfony.com/releases)
• Features and deprecations must be submitted against the 5.x branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Thank you@Matth-- for your PR. The change you propose is perfectly valid. But since the handling of sequences/mappings is totally reworked in#33763 due to other edge cases that were also failing I have added your test case there to make your that your issue will be fixed as well. So I am going to close here. Thank you for understanding.

I noticed there were multiple pr's regarding the same function 🙂.
