[Dark Mode] ToDo Notifications containing code block text render in light mode

Summary

When GitLab is set to use Dark Mode, the application fails to render To-Do's containing preformatted text in the same theme. Instead it defaults to Light Mode (or some other . . . lesser mode 😆 ).

  1. Tag yourself and look for the item in your todos.

Example Project

What is the current bug behavior?

The current behavior allows for preformatted text to be rendered in light mode on the todo page when the user has specified "Dark Mode" in the preferences pane.

What is the expected correct behavior?

ToDo's containing preformatted text should be rendered in dark mode, light fg on dark bg.
