Matomo is tracking before consent

We have a similar problem. But in our case this is only happening on live/ staging system.
Our local ddev environment is handling the consent/ rewriting done via cookies_matomo_page_attachments correctly.

On our stage/ prod the cookies_matomo_page_attachments is not working for no reason.
We also implemented a custom cookies service for matomo_tag_manager, which is working/ rewritten correctly using the same logic as cookies_matomo_page_attachments.

Should you have any ideas for the reasons, or even better a fix, please let us know.

@anybody: I do so. I'll have a closer look tomorrow and will run some tests on other machines. Hope we can reproduce the bug on another local environment to find a fix..

Smells like could be kind of a caching issue...

Even after clearing caches the problem still persists.
It's kind of strange, since our custom cookie plugin is working without any problems and the hook_page_attachments is rewriting the code correctly.
