Recently I found there was no face in the TODOs section as below.
I am using Emacs 30.2 on macOS 15.6.1. I can reproduce the issuw with emacs -Q.

Magit 20250910.2042 [>= 20250910.2042], Transient 20250910.1601, Git 2.39.5, Emacs 30.2, darwin
magit-todos-20240927.52
ripgrep 14.1.1

I am pretty sure it's fine one month ago. Not sure whether it's related to Emacs or magit upgrading.
