[Sereza7]

Jira URL

https://jira.xwiki.org/browse/XWIKI-22204

Changes

Description

• Fixed missing underlining on the inline links in the diff boxes.

Clarifications

• Since this is a specific UI and structure around the anchor, I decided to go with the solution that's the least generic and just add the helper class to this element.

We can see that all the inline links in the From version and To version blocks are properly underlined.

Executed Tests
