This year's talk "Brand New AI, Same Old Biases" (category Ethics, Society & Politics) has a very long abstract, it doesn't fit within 1080px screen height on an fhd monitor.
For legibility and usability reasons I'd like to make two suggestion:
Widen the hover-box to 1.5 of its current size towards the right, more text will fit inside, it won't feel as "cramped"
Add a timeout or margin-box to the popup so that it doesn't close too quickly. To read the last sentences of a very long abstract you'll need to keep your mouse within the hover-box and scroll, without the mosue cursor ever leaving the box (might not be an issue for a lot of people, but think of IBM/Lenovo people with trackpoint scrolling which might easily swerve left or right)
