It's interesting to see that the UX issues that are annoying me when using Azure DevOps are finding their way into GitHub.

In case they are truly chasing Azure DevOps level UX, I would recommend they implement an HTML editor for issues that, depending on whether the user has dark mode or light mode enabled, saves some CSS of the respective mode and makes it unreadable if read within the other mode.

They should also order the comments in order of recency top to bottom so you have to read the page in reverse.
