Slight delay in loading Favourites and Frequently Visited Sites

Steps to reproduce:

Expected behavior:
Favourites and Frequently Visited sites to load instantly

Orion, OS version; hardware type:
Version 0.99.109.1.5-beta (WebKit 613.1.12)
macOS Catalina 10.15.7

Image/Video:

Probably just being picky here as it's not more than a second but I feel annoyed every time I see it flash like that. In Safari, it's pretty instant.

Only happens on new windows, not new tabs.

For devs, one way to fix this is to load the favorites before creating the new window.
