Hi @iGerchak. Thank you for your contribution
Here is some useful tips how you can test your changes using Magento test environment.

New incarnation of #10965, @ihor-sviziev knows the details and will try to assist with a proper fix (i.e. when layout element is first referenced and only then created as a part of Magento_Theme layout instructions, it's position is correct just like if Magento_Theme was declared first).

@ihor-sviziev did you manage to move further on this?

[ihor-sviziev]

@orlangur unfortunately no :(

As we discussed with @iGerchak and @orlangur - it's not proper solution. We should implement fix that will prevent braking layout updates when sort order in config.php changes.
I'm closing this PR. Feel free to prepare another PR
