Fwd: issue: multiple viewer layers

Layers are not properly closed when using more than one layer, so that each
layer subsumes all subsequent content. Tested in Adobe Reader 11. I first
mentioned this at https://tex.stackexchange.com/a/467005/174577, so I'm
basically rehashing all the examples:

When \showallmakeup is enabled, all content after \viewerlayer[print]
belongs to that layer:

\defineviewerlayer[print][state=stop,printable=yes,]
\showallmakeup
\starttext
    \viewerlayer[print]{One} more.
    \samplefile{knuth}
\stoptext



The same problem as above, demonstrated with \start...stopviewerlayer
rather than \viewerlayer:

\defineviewerlayer[print][state=stop,printable=yes,]
\showallmakeup
\starttext
    \startviewerlayer[print]
        And then:
    \stopviewerlayer
    \samplefile{knuth}
\stoptext



Rather than two independent layers, the print layer (along with other
content) belongs to the view layer. So hiding the view layer hides all
content in this document:

 [view]
--- first
--- \samplefile{knuth}
--- [print]
------ second

\defineviewerlayer[print][state=stop,printable=yes,]
\defineviewerlayer[view][state=start,printable=no,]
\starttext
    \startviewerlayer[view]{first}
    \samplefile{knuth}
    \startviewerlayer[print]{second}
\stoptext

probably because it gets applied at a different stage ... but it's a 
tracing feature so normally not used with other layers

missing \stop's there .. the next at first sight looks ok here so what 
version are you running?

\nopdfcompression

\defineviewerlayer[one]
\defineviewerlayer[two]

\noheaderandfooterlines

\starttext
     \startlines
     BEFORE LAYER
         \startviewerlayer[one]
             INSIDE LAYER ONE
                 \startviewerlayer[two]
                     INSIDE LAYER ONE AND TWO
                 \stopviewerlayer
             INSIDE LAYER ONE
         \stopviewerlayer
     AFTER LAYER
     \stoplines
\stoptext

You're right, my example was broken. With \stops it works as intended, as
does your example.

Thanks,
