wiggle when selecting home in navbar

[riastrad]

For some reason, on Firefox if my browser window's height is >430, there is a small wiggle when go to or from the home option in the navbar. I've combed over the CSS and thought I had a fix, but on further inspection it seems to be caused by the presence or absence of the scrollbar on the page. Also explains why this isn't an issue on mobile or Safari.

Currently my homepage is the only one that doesn't have enough content to trigger the scrollbar when it loads. Not sure if this is worth fiddling with, or maybe I'll just add some additional links to my latest blog posts / book reviews eventually. Flagging here so I don't accidentally go down this rabbit hole again in future.
