Hello! The native mobile fixed menu is sticky where it appears on scroll down but hides on scroll up. When the menu appears or disappears, page contents shift and it causes this jump/jitter where the entire page moves up or down by maybe 50 or 60 pixels. Is there any way to disable this? It doesn’t seem to happen until after a certain breakpoint, usually just after the post title.
Thank you for pointing this out. I was sure we had this smoothed out some versions ago, but apparently we’ve missed something with all the various display scenarios possible for the mobile menu – admin bar included.
