Table layout has become totally misaligned recently

I've been on PTO for a week and when I came back all my Bugzilla tables were broken. It appears as if the table is left-aligned to the middle of the page. As a result some of the columns are off the page.

You can see an example here:

I'm not sure if a new version of Mediawiki was pushed to wiki.mozilla.org and broke this so I'm reporting it here for now. Feel free to close if this should go somewhere else.

I just reloaded my wiki page and it's now displaying like this:
