Comment (by ppurka):
Strictly speaking, this is not an error. The output of a cell has three
levels of output - let's call them ''default'', ''verbose'' and
''hidden''. The first level is the default. When there is no typeset
output, the whole output is present in the default and in the verbose
level. The output in the verbose level is what you get when you click on
the left to show extra output when some error happens. If you click it
once more you will cycle back to the hidden level. So, essentially it is
cycle like this:
{{{
default -> [click] -> verbose -> [click] -> hidden -> [click] -> default
}}}
When the output is typeset, the whole output is present in only the first
level - ''this might be a bug,'' since I think the second level is for the
verbose output and it should include whatever is in the default first
level.
So, if we follow your steps to reproduce this "bug", we will do this
1. Turn on Typeset.
2. Type `k+; 5` in a cell and evaluate
3. Click on left of the output to show verbose output
4. Remove `k+;` and evaluate
5. There is no output, so we will click to the left of what should have
been the output, but we click twice.
6. We will see the typeset 5 in the output.
