Scroll delay upon anchor link click


Strange delay on the “Books” page, when i click “hide reviews” which is a button pointing to book-one section at the top of the page, it first plays the animation (hiding the reviews) then waits a bit and only after that it scrolls.

At the same time “show reviews” button working with a same algorithm and performs just fine
