On deeper inspection, I suspect what's going on is that the Exhibit
Timeline view is out of sync with Timeline. Unless you patch the view,
it won't work; the latest version of Timeline prefers "caption" over
"hoverText" when passing in a hash for event attributes.
These lines in the Timeline default event source code ensure hoverText
is completely ignored:
this._title = cleanArg('hoverText');
this._title = cleanArg('caption');
meaning this._title will always be null if you're still using hoverText
and not caption, so you'll never see a caption in the Exhibit view.
I'll be pushing an update to fix this for 3.0.0rc1.
