[BUG] When editing the first item in a list, the rest of the list is overriden

[Nusnus]

Steps to reproduce:

1. I have this line in my file: >> - 🏷️ Tags:: #a, #b, #c, #d

2. Use MetaEdit to modify it

3. Choose #b

4. Change to #B

All is good, line was changed accordingly: >> - 🏷️ Tags:: #a, #B, #c, #d

Now that we confirmed non-first item works, let's do the same for #a

5. 
6. 

BUG! The line was changed from >> - 🏷️ Tags:: #a, #B, #c, #d to >> - 🏷️ Tags:: #A
