Description

Hello for the 1.6.4 it won't allow me to type the trace table because the font is white and I have to highlight it and it's just to much.

Reproduce the issue on the IHS_APCS topic 1.6 compound-operators page, focusing on the 1.6.4 trace-table interaction. Start by inspecting the activecode and trace-table behavior alongside the reported pretext-core.js errors. Done means the trace table's text is readable and can be entered without highlighting it first.
