Gary Illyes, from the Google Search Relations team, said on LinkedIn that Google Search handles the marquee HTML tag "appropriately." What does it mean by appropriately? That is Gary for you.

If you search for [marquee tag] in Google, you will see a new easter egg. The section that shows the number of results will scroll like a marquee board.

The "marquee" effect has been supported by HTML since the early years of the Web's rise to popularity. Using marquee tags, you can cause text and images to scroll across the screen like a news ticker.
