This patch slightly adjusts the font size of list items in the main
menu. I probably wouldn't mind making it even a bit bigger, but that's
probably worth a separate discussion.
Reasons for this adjustment:
1. Don't use different font sizes in the same lement.
While the buttons rendered at 14px, the search text rendered at 16px.
They should have the same font-size.
2. The buttons were below the base text size controlled by Tailwind CSS.
This means, it also puts the font size below the recommended
font-size for mobile devices (Google/Apple guidelines). This patch
puts them at the base level.
