Deal merge webhook doesn't work - hs_merged_object_ids

I have registered a subscription on the `hs_merged_object_ids` field in the deal, but Hubspot doesn't trigger event `propertyChange` on this field after the merge action. hs_merged_object_ids is a visible field (I changed this by API). The ability to handle merge action is necessary for many functionalities. Please help me in this case.

hs_merged_object_ids schema:


 "label"=>"Merged object IDs",
  "The list of object IDs that have been merged into this object. This value is automatically set by HubSpot and may not be modified.",
 "modificationMetadata"=>{"archivable"=>true, "readOnlyDefinition"=>true, "readOnlyValue"=>true},
