It seems improved now for most comments. But in the comment below where I posted the diagram, there occurs a very mysterious duplication that in the end clears the diagram. When I click 'View' there it first appears as it should, but half a second or so later reverts to an empty board.
When I then look at the page source, it turns out that my entire posting is in there TWICE. Only one of those apparently gets displayed. But the link to the JavaScript there is seen for the second time even in the hidden copy, and thus also executed a second time, and this apparently kills the diagram that was created during the first execution.
