Hiding the top nav on mobile devices feels extremely janky

[kantuni]

The functionality introduced in Hide top nav on reading docs on mobile feels extremely janky. Please fix the flicker when hiding or showing the top nav.

Can you record it?

please let me know if the problem persists.
However the feature only uses the transform of an isolated context. I guess it's more likely a different issue.

It looks like #902 fixed it. I can still see slight flickering, but very rarely. It might be a good idea to add some leeway before showing the header.

In any case, thank you so much for tackling this so fast!
