While it's possible for us in the gadget css file to change .tipsy-inner max-width to something higher. But that would affect all other tipsy usage (if any).
I would like the possibility on a case for case define the width of the tipsy popup, in particular for the gadget Twinkle and the CSD information popups that can be rather large sometimes.
Version: unspecified
Severity: enhancement
[Note that we bundle jquery.tipsy with core.]
I don't see any terribly useful options in the upstream documentation:
http://onehackoranother.com/projects/jquery/tipsy/#
If you could pass through a supplementary class or something that might be pretty easy to deal with.
Would need the new "className" parameter added with commit:

I have cherry picked the upstream changes and merged them in r108244.
Also asked for a new query tipsy release so we can merge all changes later on (which is bug 33562).
