[Dillo-dev] Support <dialog>, at least at the level of recognizing in CSS

Hi y’all, I realize that supporting some elements, like <dialog>, is out of scope for Dillo. However, it would be nice to recognize these elements, at least in stylesheets, so that I can at least do dialog { display: none; } Right now, the dialog is just displayed unconditionally, because, it seems, such a style rule does not apply to it. Check https://aartaka.me for an example of such dialog not hiding. So, is this it fixable? Thanks, -- Artyom Bologov https://aartaka.me
