Check the left side of the brand page. The video is trimmed and there are no H scrollbars generated. Also I think it the breakpoint should trigger much later (or earlier depending on how you look at it). At w12xx the video the issue increases even more. I'm using Chrome.

we made that as a design decision for now

No worries. I was not calling for the aesthetics of the layout. I'm actually missing letters at the left and there is no horizontal scroll bar render in the viewport
