HTML and interactive content

You can use tooltips with Jenkins Symbols too, using either the tooltip or htmlTooltip attribute. Setting both will prioritise the htmlTooltip.

Make sure that text is sanitized before displaying it inside of data-html-tooltip as this can lead to XSS attacks. Escape or avoid using it on user-controlled data like agent display names or descriptions. See Preventing Cross-Site Scripting in Jelly views.
