Sometimes setContent fails

[s7dhansh]

The first setContent always works. But while dynamically updating the content of the same infoBubble, sometimes the content does not get updated. I have been unable to figure out a step by step reproduction.

But the following works:

infoBubble.content_.innerHTML = Blaze.toHTMLWithData(tmplt, opt);
infoBubble.updateContent_();

So I assume that the setContent is not triggering these changes at random.
