This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
According to http://docs.webplatform.org/wiki/WPD:Manual_Of_Style/Gotchas#Pre_sections_with_pipe_characters, pipes should be ignored in <pre> tags. In a tutorial, I have: <pre>self.requestFileSystemSync = self.webkitRequestFileSystemSync || self.requestFileSystemSync; </pre> The page renders fine, but when I go back in to edit (?action=formedit), everything in the Content section below the "<pre>self.requestFileSystemSync = self.webkitRequestFileSystemSync ||" is lost.
Definitely just seems to be a problem in ?action=formedit mode.
Interesting. We've asked a semantic forms expert.
The workaround for now is to use ascii | for pipes in <pre>.
