render() with popover doesn't work

[codedread]

• Check if updating to the latest Preact version resolves the issue

Describe the bug
As per this link the popover attribute is available in all browser. However, I get a complaint with Preact 10.21.0: render(<div popover>foo</div):

"Popover not assignable to type htmlattributes htmldivelement"

To Reproduce

See the above snippet. Also this react bug.

Just a type error or an actual functional issue?

#4378 addresses the types

Yes, I think it's just a type error. Functionality it seems to work.
