[Makoto Kato]

Hi,

autocapitalize is an attribute to manage default capitalize state on
virtual keyboard. Although It is already tuned on Nightly, we will
ship it in Firefox 111.

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1692007
Standard: https://html.spec.whatwg.org/multipage/interaction.html#attr-autocapitalize
Standards Body: WHATWG
Preference: dom.forms.autocapitalize
DevTools: Devtools has no virtual keyboard feature
Platform coverage: All. If the platform has no virtual keyboard, no effect.
Other browsers: Supported in Blink (all platforms) and WebKit (iOS only)
