Not cropping BarChart when using Frame instead of Axes

问题

I just found out that a BarChart may get cropped when using Frame rather than Axes.

Example:

data = {.2, .4, .6, 0., 0., 0.}
BarChart[data]
BarChart[data, Frame -> True, Axes -> False]

Is this a feature or a bug? If it is a feature, is there an easy way to prevent cropping?

Well, It was not always like that:

How about using PlotRange?...

data = {.2, .4, .6, 0., 0., 0.}
BarChart[data]
BarChart[data, Frame -> True, Axes -> False, 
PlotRange -> {{.5, 6.5}, {0, .7}}, 
FrameTicks -> {None, Automatic, None, None}]

Edit

I'm beginning to think it is indeed a bug. Look what happens if we simply change the order of the elements in data. It acknowledges (but does not display the baseline of) the bars of zero height that it previously ignored. Notice that I didn't have to tweak the display using PlotRange this time around.
