Hi there,
I noticed an extra scroll bar on the browser associated with the sticky header.
When the scroll bar is at the “top”, the stick header is not visible on page scroll. But when the scroll bar associated with the header is scrolled to the “bottom”, the sticky header becomes visible again.
The z-index for the header is set to 9999 and the z-index has not been changed on the pages/sections so there’s no reason it should be behind.
I’ll add a private comment so you can check it out.
What’s going on?
