Description:
Pasting text that has been copied from other applications (Firefox, Notepad, ...) into LibreOffice (Calc, Writer) "sometimes" (not always) misbehaves:

* Instead of pasting the newly copied text from the other application, cells/contents that have previously been copied from inside Calc (or Writer) are pasted.

* This only happens when pasting into LibreOffice, but not when pasting into any other application.

* Workaround: When this happens, you can reliably re-enable pasting from other applications into Calc if you ...
(1.) select an empty(!) cell in Calc and copy it (Ctrl+C),
(2.) now copy the desired text from the other application,
(3.) and paste it into Calc. It will now work as expected.

This bug has been around at least since LibreOffice 7.4.2.3 (maybe even longer).

Steps to Reproduce:
1. Select some populated cell range in Calc and copy it (Ctrl+C).
2. Copy some text from Firefox or Notepad (Ctrl+C).
3. Now paste it into LibreOffice (either Calc or Writer).

Actual Results:
When the bug occurs, the copied contents from step 1 are pasted.

Expected Results:
The copied contents from step 2 should be pasted.


Reproducible: Sometimes


User Profile Reset: Yes

Additional Info:
You can restore correct behavior by copying an empty(!) cell within Calc. Afterwards pasting from other applications will work again.
