1493176 - :scope compat table is incomplete; it references an obsolete pref without the history

Status: RESOLVED INACTIVE

(Developer Documentation Graveyard :: CSS, defect)

Description

[Rob Wu [:robwu]]

The :scope CSS selector was once used for scoped styles, but later repurposed for querySelector.

In bug 1408106, the old documentation was removed, but a compat note about the old behavior was preserved in the compat table:
https://developer.mozilla.org/en-US/docs/Web/CSS/:scope$compare?locale=en-US&to=1319583&from=1318071

When the docs moved [1] to the new compat tables [2], some information was lost. The note about the significant change in Firefox 55 was removed, whereas the reference to the obsolete preference (layout.css.scoped-style.enabled) from Firefox 20 was kept.

I think that it would have made more sense to restore the note about 55, perhaps with a reference to style. The <style> docs is a better example of what it should be, as it has useful information about the obsolete "scoped" attribute [3].

Thanks for filing. I've opened https://github.com/mdn/browser-compat-data/issues/2911 over in BCD for this, as that's where it should be fixed.
