Handle accessibility issues related to <a> tags

[bran-van-d]

Description

We currently remove the underline for <a> tags by default which is leading to an accessibility issue, "Links must be distinguishable without relying on color". The link on the page isn't actually a different color from the default, but the lack of the underline is what creates the issue -- adding the underline back allows the link to be properly distinguished from surrounding text, passing this requirement.

We should let <a> tags have an underline by default, as users have the option to remove or otherwise edit the <a> to their liking.
