Removing unnecessary ResourceLoader modules, changing fade-overlay to
white, changing sidebar animation (before the html element used
transformx, which breaks position:fixed on WebKit so I used a JS
workaround, but now the sidebar itself transforms and
position:fixedworks fine), closing the keyboard when the search box is
closed on small. @georgebarnick I’ve been able to replicate the header
issue on all browsers I’ve tested; it looks like it has to do with the
page title being hidden. I’ll try and fix it in the next commit.
