Fix display of existing commits in the new review request UI.
Review Request #12867 — Created March 6, 2023 and submitted — Latest diff uploaded
A change in our upstream dependencies caused a regression in the display
for existing commits in the new review request UI. The old XHTML-like
<span />
was being interpreted as an unclosed tag, leaking its style
into adjacent elements.
Looked at the new review request UI and saw that existing commits had
the proper blue arrow icon but no big blue text.
