Hello @torhoehn
We discovered the next feature with this PR:
Currently if you only will hide this box, Google Analytic cookie still will not be set on this page and it will be created only if you will go to some other or refresh current.
From Marketing point of view its a problem, cause then we cannot collect statistic about which page what the first one user visited.
Maybe you can check the solution and align it in a correct way that Google Analytics cookie is set back, or revert your changes in case if its impossible to realise.
Thanks a lot!

Hi @nuzil. I did review it again. For me it looks like that the pageview will be recognized and it doesn't matter if the cookie notice will be closed by the user or not. So it's just a hint without any functionality in the background.
