Increase the minimum target sizes

Problem/Motivation

The target sizes for toggle icons and token links in the token browser don't have the minimum dimensions of 24 by 24px required to meet WCAG2.2 SC 2.5.8 (https://www.w3.org/WAI/WCAG22/Understanding/target-size-minimum.html). The purple dots represent elements not meeting the minimum target size.

Steps to reproduce

• Add the bookmarklet to your favorite bar https://html5accessibility.com/stuff/2023/08/28/quick-and-very-dirty-tar...
• click the browse available tokens link on a page that contains it
• start the bookmarklet

Proposed resolution

Increase the target sizes so that at least the minimum required dimensions are met.
