The console output of p4 interferes with the output wrangling done by plugins like timestamper or ansi color, because those cause p4 output not start at the beginning of the line. The assumption it always would is unfortunately hard coded into p4 plugin by using a div for the expandable sections.

Using a span instead of a div would fix this. Changes would be required in P4ConsoleAnnotator.java lines 33 and 46, P4ConsoleNote/style.css line 1, webapp/style.css line 1. Actually, for backwards compatibility with already created console notes, the style.css files should be extended for the span.
