Error when copying pages in a subwikis

I get the following error when trying to copy a page in a subwiki

No row with the given identifier exists: [com.xpn.xwiki.doc.rcs.XWikiRCSNodeContent#com.xpn.xwiki.doc.rcs.XWikiRCSNodeId@5eb1916[docId=5614372608613626525,version=2.1]]: [<null entity name>#<null>]

The destination page will be created but it will not contain any of the content or objects of the source page

I initially thought I had misconfigured something as we had upgraded from v12.5 to 14.3.1 but after much trial and error I ended up trying the demo versions of xwiki and I was able to somewhat reliably replicate the issue in a fresh install for each of these versions 14.3, 14.3.1 and 14.4

Steps that can reproduce the error:

1. Download and run either version 14.3, 14.3.1 or 14.4 of the “Standard Flavour Pre-installed”
2. Create and go to a subwiki
3. Create a page in subwiki
4. Copy created page and then get error

Notes:

1. sometimes you don't get the error, but if you try copying the page you just copied, or create a new page and then copy it, the error is likely to appear again
2. from my testing this issue only seems to affect subwiki's as it doesn't seem to be an issue on the main wiki
3. if the error appears listing a version that is not the current version, just viewing the revision seems to fix the issue temporally for that page
