Don’t know if this is what you are talking about. But if you drag the sidebar on desktop mode, this one overlaps the content and after releasing it the content adjusts it self in a awkward way to match layout. This does not happen if you click on the hamburger button.

Ex.:

I record the screen as a .mov file using Quicktime Player, I use Mac os.
I cannot upload the mov file here, so I shared in my Google Driver as:

please see that.
