Could you use CSS class "hidden" for this instead of
directly manipulating the style?

Setting the class="hidden" on the html element by default
and

$('ownerOnlyWarning').classList.remove('hidden');

here would work, I think.

(The .hidden class is defined in options_page.css)

Good idea. Done.

       this.addEventListener('visibleChange', this.handleVisibleChange_);
