I recently integrated the Light Face plugin by davidwalsh into my project, which allows me to load content from another page. However, I encountered an issue when trying to implement mootools tooltips on form elements within the loaded content. The tooltips were not displaying properly within the light face dialog. Interestingly, when I removed the lightface.css file, the tooltips appeared as expected. It seems like there may be a css error causing this problem, but as a newcomer to css, I am having trouble identifying the issue.
