I noticed some weird behaviour after the last update.
This one is about the viewport media query for tablets. I realized that there is a gap between 8-10 px within the media query, that I cant adress nor can I style my elements.
I hope that I can link to a video that will explain that problem:

I can change the styles within the designer, but it is not applied to the layout from 983px to 991px (Tablet View).
