Hovercards get "stuck" on quick mouseover events

[Daeraxa]

Thanks in advance for your bug report!

• Have you reproduced this issue in incognito/private browsing?
• Have you made sure you issue doesn't already exist?

Where is the URL that this occurs?

Exact page is unimportant but for the sake of the template https://docs.pulsar-edit.dev/api/pulsar/latest/ (or almost any API page) can be used to demonstrate as it has abundance of these types of links. This does also happen on normal docs pages such as https://docs.pulsar-edit.dev/core-packages-and-features/

What's your issue?

Basically if you slowly mouseover a link then the hovercard will appear, then if you move off again the card will vanish (which is the expected behaviour).

But if you do this very quickly the card will appear and remain on screen. The only way to then get rid of it is revisit the same link (or another one) to reset the card.

Which OS/Browser/Version does this happen on?

Fedora 43
GNOME 49.5
Wayland
Firefox 149.0.2
