Bad layout execution from reaction with salts, when exporting RXN V3000

**Steps to Reproduce**
1. Open ketcher (I use the online demo version 3.12)
2. Draw a reaction where a reactant contains a salt. See below for my example:

here is the RXN V3000 format corresponding to that reaction:

original RXN

```
$RXN V3000

3. Apply the layout to rearrange the scheme. Here we obtain this below, which seems correct:

BUT the RXN V3000 is missing the first reactant:

Which leads to that structure:

If I redo the same operation but I remove the salt (HCl) in the second reactant, I get the right RXN V3000 structure
