Attachments: Screenrecording of copy (CTRL+C) not working when an image is in the clipboard

Description Alexis Murzeau 2023-06-27 19:35:32 UTC 
SUMMARY

Copying something after having an image in the clipboard will clear the clipboard instead of copying.
This happens only when the clipboard history is limited to 1 entry.

STEPS TO REPRODUCE
1. Configure the clipboard history to have:
  - 1 entry history
  - See video for all other configuration, but I'm don't think that's need beyond the history depth
2. Press `PrtScn` key to open Spectacle
3. Click on the Copy button of Spectacle repeatedly.
  - This will alternatively put the image in the clipboard and clear the clipboard.
4. Click on the Copy button of Spectacle so the image is in the clipboard
5. Copy a text, this will clear the clipboard instead of copying the text
6. Try to paste, nothing is pasted as the clipboard is cleared (expected: the copied text should be pasted)

OBSERVED RESULT
See video in attachment that show how to reproduce.
When the clipboard is cleared unexpectedly (when copying something while having an image in the clipboard), the copied object (image or text) can't be pasted (which is probably explained by the fact that it cleared the clipboard instead).

EXPECTED RESULT

When copying something while having an image already in the clipboard, it should be replaced with the newly copied stuff (even if the history depth is only 1 entry).

OK so there is an option in your video which is important which is "Non-text selection: Never save in history".

So when I set history size to 1, and select the Never save in history option for Non-text selection, then this issue occurs.

Confirmed on Plasma git master.

I'm not sure since which version, but I've tried to reproduce this bug (I still have the same settings) and everything works correctly.
Copying text after an image or image after text is working correctly.
