New comments don't show math without refresh, as well as preview mode

[orsharir]

At the moment there's a bug that after adding a new comment to an issue or editing an old comment, the math in the comment is displayed as plain text. Should watch respective events and update math display.

Similarly, should add support for preview mode of the editor.

You can add this code to update the page when the preview tab is hovered, or active:

// "preview:render" only fires when using the hotkey
// "preview:setup" fires on hover & click of comment preview tab
document.addEventListener("preview:setup", function() {
  setTimeout(function() {
    // must include some rendering time...
    // 200 ms seems to be enough for a 1100+ line markdown file
    MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
  }, 500);
});
