Odd behaviour with Fluid fields and Field groups on cloning an entry

[jcogs-design]

Description of the problem
Have setup a number of Field Groups that are then referenced by a fluid field.
In normal use this allows me to define page content that re-uses a number of base level fields repeatedly in different field-group contexts. For example in this page you can see multiple instances of the "Fluid text plus image" field group.

However when this entry is 'cloned' you can see that the field group "Fluid text plus image" is broken by the process - what were blocks of three text fields followed by two images now has a series of incomplete / broken field groups (alternating between having two images and three text fields). You can see similar breakage to the field group "Fluid client quotes element".

How To Reproduce
As described above

Environment Details:

• Version: 7.4.10
• PHP Version 8.3

Possible Solution
Adding new instances of the field group from the fluid field fixes the issue on a per-fieldgroup basis, but it would be better if the cloning worked properly.
