BUG OpenNext command preserve isHyperstack flag from previous image

[Schebique]

Hello.

I noticed that if I use Open Next command for single plane 8 or 16 bit
images (.dcm in my case, but doesnt matter) when the first one was changed
to hyperstack, the Stack.isHyperstack macro command returns true even that
newly open (next) image clearly could not be. Here is a minimal macro
demonstrating the problem. You only need a folder with at least two single
plane 8 or 16 bit .tif files.

//originally this occure to me with MRI .dcm files
file=File.openDialog("choose first of 8 or 16 bit single plane images.
There must be at least 2 in folder");
open(file);
n=nSlices;
//if (is("composite")) print(getTitle()+" is composite");
if (Stack.isHyperstack) print(getTitle()+" is hyperstack");
else print(getTitle()+" is not hyperstack yet");
run("Add Slice", "add=channel");
run("Add Slice", "add=channel");
run("Stack to Hyperstack...", "order=xyczt(default) channels="+n+2+"
slices=1 frames=1 display=Composite");
print(getTitle()+" is converted to hyperstack now");

run("Open Next");
if (Stack.isHyperstack) print(getTitle()+" is marked as hyperstack and
should not be!");
else print(getTitle()+" is not hyperstack");

-------------------------------
my log says...
Mik101_Ti_sin1224-8bit.tif is not hyperstack yet
Mik101_Ti_sin1224-8bit.tif is converted to hyperstack now
Mik1056_Ti_sin1414-8bit.tif is marked as hyperstack and should not be!

This bug is fixed in the latest ImageJ daily build (1.51b23).
