This App just Suddenly Forgot how to Read Issue Comments

I've been using this app just fine. And then all of a sudden I can't read issue comments. I've spent 3 hours on this.

Start by reproducing the failure in GitHub App 1.1.12 on macOS 26.6.2, using the GitHub theme and the root path shown in the report. Compare issue views where comments are readable with the failing view; done when issue comments render reliably in the affected setup.
