Subset editor: internal clipboard is cleared after each paste
** Key Information (please complete the following information):**
- Arc Version: 4.1
Describe the bug
When using copy/paste in the subset editor the clipboard is cleared on each paste operation. This is really annoying and in inconsistent with how the clipboard works in other applications. E.g. for a scenario where there is a new element which you want to add to several static subsets, the user needs to re-copy the element after pasting and updating each subset. This shouldn't be the case.
To Reproduce
- Copy an element(s) in subset editor
- Paste the element(s)
- Attempt to paste again. You can't becasue the paste has cleared the clipboard
Expected behavior
Paste action should not clear clipboard
