Screenshot

Notice the barely-visible black cursor at the end of the fmt.Println() statement. It looks like the color was selected for the light mode and never adjusted for dark mode. Below is the same cursor in light mode.

What did you do?

1. Visit tour of go.
2. Turn on dark mode.

What did you expect to see?

A clearly visible cursor.

What did you see instead?

See screenshot above.
