For each code block it checks the source. If the check refuses it, the block loses its formatting and its starting line number. The check reports which block it was, where it came from and what was wrong.\n\n**Why**\n\nThis adds a safeguard on code blocks shown on screen, for example ones that plugins display.\n\n- Area: UI Protocol\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
