Describe the bug
I expect the code preview in "Terminal Font" to help me preview how code would look, including having box characters line up. Instead, they are not lined up.
This seems to be a mistake when previewing primarily monospace fonts, where the goal is for characters to line up.

The above code block looks similar to the preview I am seeing in the Superset app:
