1955379 - Enable about:config pref 'dom.hidden_until_found.enabled'

Status: RESOLVED FIXED

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

Description

[Daniel Holbert [:dholbert]]

Bug 1761043 ("Implement hidden=until-found attribute and beforematch event") is adding its implementation behind a new about:config pref dom.hidden_until_found.enabled which is disabled by default for now.

Filing this bug on enabling that pref by default. If we find issues that we need to address before shipping, we can mark them as blocking this bug.

(If it turns out we need to enable this behind a nightly-only guard first, we can spin off another bug for letting it ride the trains to release.)
