This appears to be a website bug. It provides invalid HTML by not properly terminating some <em> tags and it also reverses their use in some places too, which makes Firefox construct the document incorrectly. Everything under "Debugging Network Manager" inadvertently ends up as a child of an <em> element in the DOM, and inherits its styling from that (which happens to be italics).
Eg: If a network-manager bug report is about not being able to connect the title or summary should be in the format: </em>[CHIPSET] cannot connect to (ENCRYPT_METHOD)<em> where the CHIPSET is the wireless driver used and ENCRYPT_METHOD is the encryption method used by your wireless network. ...looks wrong to me. I manually edited the HTML locally by correcting the reversed <em> tags, and it displays correctly. ** Changed in: firefox (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716829 Title: firefox 4.0b11 does not display MoinMoin markup correctly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
