<span> does not need to bind to a pref. Since you have i18n-content on <label>,
this <span> is probably not needed.

[Tim Song, 2013/10/15 22:23:31]

Don't we need this controlled-setting-indicator to do a bubble pop-up if the
preference has been changed through sync?

[xiyuan, 2013/10/15 23:59:37]

I see. Totally missed that.

This <span> could be removed too.

[Tim Song, 2013/10/15 22:23:31]

Don't we need a bubble here here as well?
