Description:
I am trying to copy some elements from one libreoffice presentation to another and I am finding out that it is not anymore possible.  This is a very serious issue.

I am experiencing the problem on linux KDE plasma desktop, KF6 VCL.

When I copy and paste, the pasted item is invariably a bitmap, even if the source was an editable object. If I try to paste as special, often only the bitmap format is proposed. In some cases you get other formats too but this is erratic. When you get these other formats, more often than not things still don't work as expected, since the pasted elements are incomplete.

I think I remember that there was recently a problem with LibO usage of the clipboard which caused libreoffice to crash. I don't remember if the issue was "fixed" on the LibO or the Plasma side, but the "fix" may be the reason for the current behavior.

Steps to Reproduce:
1. Open two presentations
2. Try to copy multiple elements at once from one to the other


Actual Results:
You get a bitmap

Expected Results:
You should get the original objects


Reproducible: Always
