DOM Update 2025-06-18 #61986

jakebailey · 2025-07-02T00:28:08Z

5.9 is a little late, and a bunch of DOM doc improvements have been made.

Update to the DOM lib as 2025-06-18 at https://github.com/microsoft/TypeScript-DOM-lib-generator/tree/99c595280da56d2d1e4c44c5c2d6241042d0da42. I'm choosing this slightly older commit on purpose in order to avoid pulling in the partially incomplete CSS type changes still happening in that repo.
