Research direction

Start with the HTML specification's ImageData array section and the current generated @types/web ImageData constructor definition. Compare the accepted data types with the cited Chromium and WebKit implementations. Done when the generated type definition accepts Float16Array for the constructor and the relevant checks pass.

Written by the indexing model from the issue text.

Description

lib.d.ts bug
Summary

Missing type in constructor

Expected vs. Actual Behavior

This is a fairly recent change, the ImageData constructor now accepts Float16Array as type for data in it's constructor, see:
https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#imagedataarray

There already is an issue on MDN to reflect this.
