Vanilla plugin: Show a mentioned user's previous comment in a tooltip.

Hovering over a mention in a comment will open a tooltip showing the previous comment the referenced user has written in that discussion (if any). Aditionally, the referenced post is highlighted if it is visible in the viewport.

This mechanism works across pages.

Since users often use mentions in order to reply directly to another user, this can be used as an effective replacement for a quote system.

  // Maximum width of the tooltip (pixels).
  $Configuration['QuoteMention']['MaxWidth'] = 350;
  
  // Position of the tooltip (top, bottom, left, right, top-left, ...).
  $Configuration['QuoteMention']['Position'] = 'bottom';
  
  // Show a progress indicator until tooltip contents are loaded.
  $Configuration['QuoteMention']['ShowProgress'] = true;
  
  // Maximum length of the content shown in the tooltip.
  $Configuration['QuoteMention']['MaxLength'] = 400;

Use the .tooltipster-vanilla class to style the tooltip and .mentionHighlight to change the highlight effect.
