JOSM shows wrong field when clicking into a field to edit a tag

[GerdP]

(see also ​http://gis.19327.n5.nabble.com/Is-JOSM-responsible-for-tags-like-layer-Main-Street-tt5860983.html)

During the last days I've corrected many tags like
layer=Carrer de Rocabertí

where it is quite obvious that the mapper wanted to use
a different tag key.
There are still many more cases,
e.g.
layer="Dale Farm Road"
surface="Place de la Liberté"

I was sure that these errors were produced by the mapper by
clicking into the wrong field before editing, but yesterday I found
that JOSM really showed the wrong field. I was able to reproduce the
behaviour:
Click on name and the lanes field are shown, click on lanes and the name
fields are shown. I did that several times, made sure that I really hit the right
field, so the error is there.
It happened after an update of JOSM to version 9060, so I thought I should
report this ASAP. I thought best is to report everything I did, so I stopped JOSM,
started it again and tried to reproduce the problem, but it was gone and did not
appear again since then.

I hope the programmers can find the cause of the problem, if any of you
experiences the same behaviour, please report it.
