selective copy paste: copy from lower instance of module overwrites higher instance on paste

[wpferguson]

Describe the bug

If you have 2 instances of a module, change the lower (in pixelpipe) instance, then copy and paste it to another image with both instances, the higher (in pixelpipe) instance is changed. If the instance has a label, the label is not changed so there isn't an indication that the incorrect instance got the change applied to it.

Tested the copy both instances work around that I found with #16375 and it works here also.

Steps to reproduce

1. Open an image with 2 instances of tone equalizer and change the lower to compress dynamic range.
   

2. Selectively copy the lower instance.
   

3. Paste the copy and then notice the upper instance changed, but the label remained the same.
   

Expected behavior

apply the change to the corresponding instance

This is expected to me or there is something I don't understand. If you copy a single instance then when pasting we see a single instance which gets pasted :

• In the first non hand named instance
• Or in a new instance is all instances are named

I can't reproduce it with #16373
