Details:

• Which browser: Edge
• Codeforces++ version: v2.3
• I am using the
  • [ ] Browser Extension
  • [ ] Userscript
    • My userscript manager is: [e.g. Tampermonkey, Violentmonkey, ...]

Additional context At first the color is colored, I read the web log, changing shows up after Codeforces' log: Initialized window.changedTests.. Codeforces++'s log, Codeforces++ is running! shows up before that. So I guess Codeforces++ finished its work, but Codeforces override it. Maybe it's not right, just an idea.
