Appearance of reactions (plus and arrow) is changing after applying the layout Server function

[ZhannaNovikova]

Case 1
Steps to Reproduce:

1. Execute the /v2/indigo/layout with the following parameters:
   struct:
   structure with reaction arrow.zip

options: {
aromatize-skip-superatoms: true
gross-formula-add-isotopes: true
gross-formula-add-rsites: true
ignore-stereochemistry-errors: true
mass-skip-error-on-pseudoatoms: false
smart-layout: true
},
output_format: "chemical/x-indigo-ket"

Case 2
Steps to Reproduce:

1. Execute the /v2/indigo/layout with the following parameters:
   struct:
   structure with reaction of the plus and arrow.zip
   options: {
   aromatize-skip-superatoms: true
   gross-formula-add-isotopes: true
   gross-formula-add-rsites: true
   ignore-stereochemistry-errors: true
   mass-skip-error-on-pseudoatoms: false
   smart-layout: true
   },
   output_format: "chemical/x-indigo-ket"

Expected behavior:
Response is received with correct reaction structure, e.g:
Response from Remote mode.zip

Actual behavior:
Appearance of reactions (plus and arrow) has been changed after applying the layout Server function

Note: the issue is reproducible in the Standalone mode only
