Description:
I have a reproducible bug with LibreOffice (since months already, I just come now to report it. The problem just occurs when I copy and paste with the UI (selecting via mouse, right click on selection and copy it -  afterwards going to another document, right click and paste it). The problem is as following:

I open a new writer document (*1) and create a document with 3 lines and the text:

Line1
Line2
Line3

Seperately I open another new document (*2) which is blank and just there to insert the copied lines (also via UI pasting)

1.
(*1) I select line 1 and copy it (via UI) and paste it in the new document (*2)
--> works as expected
--> In the new document (*2) I press enter to add a new line


2.
(*1) I select line 2 and copy it (via UI) and paste it in the new document (*2)
--> nothing is pasted
--> In the new document (*2) I press enter to add a new line

3.
(*1) I select line 3 and copy it (via UI) and paste it in the new document (*2)
--> works as expected
--> In the new document (*2) I press enter to add a new line

4.
(*1) I select line 1 and copy it (via UI) and paste it in the new document (*2)
--> nothing is pasted
--> In the new document (*2) I press enter to add a new line

5.
(*1) I select line 2 and copy it (via UI) and paste it in the new document (*2)
--> works as expected
--> In the new document (*2) I press enter to add a new line

5.
(*1) I select line 3 and copy it (via UI) and paste it in the new document (*2)
--> line2 is pasted
--> In the new document (*2) I press enter to add a new line

6.
(*1) I select line 1 and copy it (via UI) and paste it in the new document (*2)
--> works as expected

I have uploaded a screenrecording of the problem here:

Steps to Reproduce:
See description above --> copy and paste with UI

Actual Results:
Paste does not happen / happen in wrong order / not happen

Expected Results:
Normal copy paste, as when using the keyboard shortcuts


Reproducible: Always


User Profile Reset: No



Additional Info:
Happens on Arch Linux since several months using "libreoffice fresh" on several installations. All installations use Gnome 3, some run on Wayland (and intel graphics), some on X11 (using proprietary NVIDIA graphics driver)
