Accordion: heightStyle: 'auto' has problems with parent div width and box-sizing

[EleventyOne]

I'm using Firefox 20.0.1 on Win 7 64. There appears to be two problems with the accordion widget, when heightStyle : 'auto':

(1) If a parent div has a width set, 'auto' seems unable to properly calculate the height of certain accordion tabs.

(2) If box-sizing: border-box is set, there is a nasty "snap" to the accordion tabs at the end of their being displayed.

If you change heightStyle to 'content', both problems disappear.

This problem is demonstrated here:

And was asked about on StackOverflow here:

Confirmed both. This should probably be split into two separate bugs but I'm going to dig into this a bit first.
