TOC has died / disappeared in the responsive HTML5 output, it's available in smaller views, but not in full screen.
Basically get a Loading... prompt and nothing is happening. I'm near the end of a sprint and don't have the time to figure out what went wrong. Hoping someone can help...
However it's fine in other views (smartphone/ tablet etc...)
This happened out of the blue with no tinkering to the TOC. Please Help! Thanks...
