Duplicated cell issue. (on hold)

Something inherited from nip2.
Looked if I could find anything related in nip2 and nip4 (Issues & TODO) but did not find anything seemingly related.
Thought I had read or wrote something about it (before nip4 came around), but apparently not.
As it seems to have never been reported. I fear its just one other very specific local nip* problem.

The general issue with copies of duplicated cells is that they don't stick to any setting changes that are made to them.
Initially the cell-copy seems to work ok with the new settings. But when they are auto-recalculated (when something was changed in there input source/path) they flip back to displaying & using there default values.

So far the only way to get those cell-copies to work normally again it to change the cell command (ie: inputting some nr +enter, and than restoring the initial command+enter). Which, apart from the problems they give, also kinda defeats the whole point of using the 'duplicate-cell' feature. (_not sure at this moment if saving and reloading the workspace got rid of these issue. Think I checked, but that was a long time ago/ - Yes: it did.)

Image:

• A+C: Is both before and after B.
• B: Opened same setting, and closed them with a ENTER.
• • Any real 'setting change' will be picked up by the cell ... but only until the next re-calculation comes along.
• • (cell A10, directly above A4 in image, was the duplicated cell. With A4 being the copy. A immediately created copy of A4 turned up with its default setting.)

Reproduce the duplicate-cell scenario described for cells A4 and A10, changing a setting and triggering recalculation by changing the input source or path. Check whether the setting is retained after recalculation and after saving and reloading the workspace; the issue provides no file or test entry point.
