[Bug 1891629] [NEW] okular snap: emacsclient does not work

[Daniel Meyer]

Public bug reported:

1) release: Ubuntu 20.04.1 LTS

2) package: okular snap, 20.04.0, from latest/stable
and okular apt 4:19.12.3-2ubuntu1

3)
okular snap package (for 20.04) does not support emacsclient correctly. In settings -> Editor "Emacs client" was selected. However, shift-click on a pdf did not invoke emacs as expected. The command

emacsclient -a emacs --no-wait +100 file.tex

from a terminal did work. I removed the snap okular package and installed the apt okular package via synaptic. Here emacsclient does work, has the expected behaviour. 
A possible reason for the problem is that emacsclient is only invoked when the "Tools -> Browse" is selected. While I did select this in okular-snap, the mouse cursor does not change to "hand", as it does in okular-apt. 
Emacs was installed from synaptic, i.e., as apt-package.
