CMS-App rendering not as expected

[NinjaArmy]

PHP Version

7.4

Shopware Version

Shopware 6.4

Expected behaviour

Within the blocks you define slots for the elements with slot names. The expected behaviour would be that the first slot you define in a block will be rendered first.

Actual behaviour

The actual behaviour is that the slots in a block are rendered alphabetically. There is no information for this in the docs.

How to reproduce

Clone the repository https://github.com/NinjaArmy/sw6-cms-app-example and take a look at the behaviour. 2 blocks complete identical but the slot names are different. Also there is a detailed description in this repository
