According to the Lighthouse report the Projects page has almost 2500 nodes while the recommended maximum is 1500:
Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
We should find a way to decrease the number of DOM nodes.
