This happens both in the Desktop and inside Thunar.

Successful replication of this bug can be made if you follow these steps.

Pay attention to the mouse arrow in steps 2 and 5.

I have done this today exactly like written below.
And took the following 14 screenshots:

---------------------------------------------
step 1

debian-9.11.0-amd64-xfce-CD-1.iso
in Virtualbox, install Debian 9.11 9 XFCE
and activate a mirror during installation for upgrades
so that the final result is a Debian 9 fully updated system

step 2

without changing anything at all (themes, config files, etc), do this:
- in the Desktop, right-click in upper half of the screen
- in the Desktop, right-click in lower half of the screen
- open a folder with Thunar and right-click in upper half of the screen
- open a folder with Thunar and right-click in lower half of the screen

---------------------------------------------
step 3

- create a lot of Thunar custom actions

I have created 100 in this test, which are in fact the same (just a simple
"mkdir screenshots")

if you prefer, you can use the attached file (uca.xml) to replace the default
custom actions file

default custom actions file location:
/home/YOUR-USER/.config/Thunar/uca.xml

---------------------------------------------
step 4

- logout
- login
to be completely sure that the new custom actions file will be work both in the
Desktop and in Thunar

---------------------------------------------
step 5

after logging in, do this again like in step 2:
- in the Desktop, right-click in upper half of the screen
- in the Desktop, right-click in lower half of the screen
- open a folder with Thunar and right-click in upper half of the screen
- open a folder with Thunar and right-click in lower half of the screen

---------------------------------------------
At this point, as anybody that performed these steps will see, the problem is
that a menu entry (which in fact is a command) of the right-click menu is
automatically selected by default.

To my knowledge, this does NOT happen in other file managers in Linux or
Windows or BSD or Apple.

Nautilus and PCManFM also have custom actions and that does NOT happen in them,
as you can see here (also tested in the same Debian 9 system):

Nautilus

http://imgbox.com/QuUt6oIa

PCManFM
http://imgbox.com/YfK01K2A
http://imgbox.com/7s0cR7BD

I can only understand the right-click menu automatically selecting a menu entry
by default in special situations:
- if there are NO custom actions present
- if the user wants it and set it so

To fully understand the bad consequences of this, please read what I wrote
above in the forum post at time "2020-01-14 09:45:40 WET"
