that is normal. all tjhese apps say they can load a pdf, so they are on the
list of candidates. one of the candidate list is chosen by e - whatever it
finds first in its in-memory data structures, UNLESS you have explicitly set
one via settings OR used efm to "open with" a specific one, then that is used.

i tested this myself just before i wrote my last mail and xdg-open followed
what enlightenment_open does...

perhaps your system's xdg-open is old and doesn't support enlightenment? try
using enlightenment_open instead .... it should be consistent.

the xdg tools are heavily hard-coded for specific desktop support. xdg-open is
just a shell script, so have a read :) perhaps you need to upgrade OS/XDG tools?

well then you get the settings dialog with the massive list of mime types to
have fun with. :)

it is possible the app is not using xdg-open and doing its own thing
(enlightenment does its own thing ... well chicken-and-egg problem. xdg-open
these days relies on enlightenment to do the opening and  e will use
~/.config/mimeapps.list | ~/.local/share/applications/defaults.list files
(mimeapps first if found, otherwise fallback to defaults.list). e will write
all config these days into the mimeapps.list file. some time ago (i don't know
when) xdg decided to change from the defaults.list file to the mimeapps.list
scheme. e will auto-upgrade you to the new scheme if you don't have a
mimeapps.list file bu just copying defaults.list over to there. perhaps it's
something related to some apps using the sold scheme and some the new, maybe
xdg-open not supporting enlightenment ... perhaps a combination of the 2?
