All 3 Collapsibles contain the text "May the force be with you" but only the content in the 2nd and 3rd Collapsible will be revealed by the browser's in-page search (e.g. Ctrl/Cmd-F) in supported browsers

All Collapsibles here are animated, but if they are opened by find-in-page, the opening animation will be disabled (one-off) and open instantly

Collapsible #2 is animated using CSS @keyframe animation, while #1 and #3 is animated with CSS transitions. #3 demonstrates a possible browser bug where the matching text is not properly highlighted by the browser the first time that instance is matched. It only occurs with transitions, not @keyframe animations.
