New page navbar clicks have 1/4s glitchy flashes

Problem

When I click on a toctree nav link to a new page, there's a 1/4 second glitchy flash:

If you look carefully, it seems to jump to the top, then jump back to the selected nav.

Reproducible Code

.. toctree:: 
   :maxdepth: 1
  
   foo1
   foo2
   foo3

Expected Results

Expected smoother transitions
