_in_query is not working for Dimension when using it in COUNT custom field

[Vitaliy]

I face an issue with _in_query to properly define sql_table_name. It is not working when dimension is used in Custom field. 

Scenario: 
1. I defined sql_table_name for a view with liquid and _in_query
  {% if bonuses_daily.account_id._in_query %}
  `tangome-production.finance.bonuses_daily_account`
  {% else %}
  `tangome-production.finance.bonuses_daily`
  {% endif %} ;;

2. When Account_id field is used in filter or returned in table that is working fine. I see SQL than references proper table bonuses_daily_account
 

3. When I use dimension menu for Account_ID field (three dots) -> AddCustom Field → Count the resulting SQL references wrong table bonuses_daily. 
 

4. When I create measure in the Model that counts Account ID’s that is also working fine. 

   

   
   
   Question: is it a bug or a feature? Can it be fixed?
   
   I expect that there is no such issue. This is bad for users as they can make custom field and find themselves looking at errors. 
   I want to focus on modelling and not on explaining users how to use COUNT properly.
   _in_query is wonderful feature, but such a issue ruins the whole idea
