1836210 - Warn when setting document.domain

Status: NEW

(Core :: DOM: Core & HTML, enhancement)

Description

[Simon Pieters [:zcorpan]]

We'd like to make document.domain setter do nothing by default, see https://bugzilla.mozilla.org/show_bug.cgi?id=1817844

That end, it would be good if devtools console issued a warning when document.domain is set. It can link to https://developer.mozilla.org/en-US/docs/Web/API/Document/domain

I think this can be done setting the proper Decprecated tag in the webidl, see https://searchfox.org/mozilla-central/rev/8dd0d2bebe4c897152da6c86d937e4be80bbaa54/dom/docs/webIdlBindings/index.md#1796-1808

Yeah, I think this just requires some DOM side changes. There's some documentation about it here.

Well, maybe Deprecated won't work because we only want it for the setter, but I think that would still require DOM side changes.
