Clipboard history test

SUMMARY
Sometimes, when copying (either if it's CTRL + C or Right click, copy), it will copy nothing.

STEPS TO REPRODUCE
I was not able to re-produce the issue inside a VM.

OBSERVED RESULT
Sometimes, when copy pasting, the clipboard appears empty (wiped or contains nothing).
Looking at clipboard history, last item after the issue appears, is blank text, nothing.
Testing within a single application, it seems like once you have copied nothing, the next time you copy, it will work. It alternates between copying nothing, and copying the text.
Testing between different applications, sometimes it copies nothing (clipboard item is nothing), sometimes it copies the text, and sometimes the copy doesn't copy (clipboard does not update)

EXPECTED RESULT
Copy to clipboard should not copy nothing, and should copy the text selected.

There were many clipboard improvements in 5.23, I believe this one should be fixed as well. If you're able to reproduce it in 5.23, please reopen this bug report.
