Specification

https://github.com/whatwg/html/issues/8216

Summary

The scrollPathIntoView method on CanvasRenderingContext2D was implemented in Chrome behind a flag, but never shipped and never implemented by any other browsers in the nearly 10 years of its existence. The WHATWG has agreed to remove the method due to lack of interest. It has zero usage according to the stats, and MDN says it is not implemented anywhere. We are removing the method and associated flag and tests.

Motivation

The scrollPathIntoView method has been in the spec since 2011 and no browsers have shipped it yet, though there is an experimental implementation hidden behind a runtime flag in Chromium. There seems to be no implementer or web developer interest for this feature: No usage reported in chromestatus No related outstanding issues in the chromium issue tracker. No activity on the WebKit issue until it was just closed: https://bugs.webkit.org/show_bug.cgi?id=149987 Firefox bug has been open for 10 years with no activity: https://bugzilla.mozilla.org/show_bug.cgi?id=1120401 It was agreed by WHATWG to remove the method after a suggestion from Justin Novosad, and there is even a WPT test ensuring it is removed (https://wpt.fyi/results/html/canvas/historical.window.html, "CanvasRenderingContext2D.scrollPathIntoView method is removed"). It has now been removed from the spec and from MDN.

If this method was only ever enabled behind a flag, I don't think this removal requires any API owner approval. Happy removing!
