Can someone explain the following behavior exhibited by a combination of SetDelayed, Dynamic and Histogram.

Take

example := RandomReal[{0, 100}, 100]

and compare

Dynamic@Histogram[example]

with

Dynamic@Histogram[{example}]

Use case:

I would have expected Histogram to behave similar to e.g. ListPlot i.e. compare

Dynamic@ListPlot[{example, example}]

and

Dynamic@Histogram[{example, example}]

Since Kuba noted in a comment that he can reproduce this behavior in version 10.4 but not 11: I am using Mathematica 11.0.0.0 on OS X 10.11.6

I believe it was asked before, can't find it. Can reproduce it in 10.4, can not in 11. – Kuba Jan 18 '17 at 11:43
@Kuba I though that this must have been asked before because it is so basic but I couldn't find anything either – Sascha Jan 18 '17 at 11:48
I can confirm the same behaviour in version 11.0.1 on OS X 10.11.6. – Jacob Akkerboom Jan 24 '17 at 12:27
Also compare Dynamic@{Histogram[example]; First@example} and Dynamic@{Histogram[{example}]; First@example}. – Jacob Akkerboom Jan 24 '17 at 15:00
