Angular schematics generates blank lines through template

Riproducete le righe vuote dal template schematic inline <% ... %> usando npm run build e schematics .:ui-generator --name=hello. Iniziate tracciando il modo in cui Angular CLI schematics esegue il rendering dei comandi del template, quindi verificate che l'output generato ometta gli spazi bianchi appartenenti solo ai comandi, preservando al contempo il contenuto circostante.

Command

generate

Description

I have ng schematics template __name@dasherize__.component.html with content :

<% for (let row of getComponents().rows) { %>
<div class="row">
  <% for (let field of row.fields) { %>
  <% if (field.type === 'InputStrxing') { %>
  <field labelCode="code" class="col-sm-6 col-md-3">
    <input name="code" ngModel [readonly]="readOnly">
  </field>
  <% } %>
  <% } %>
</div>
<% } %>

I build it with :

npm run build 
schematics .:ui-generator --name=hello

Generated code creates empty lines on place where is put command "<%" in template, see:

<div class="row">
  
  
  <field labelCode="code" class="col-sm-6 col-md-3">
    <input name="code" ngModel [readonly]="readOnly">
  </field>
  
  
  
  <field labelCode="code" class="col-sm-6 col-md-3">
    <input name="code" ngModel [readonly]="readOnly">
  </field>
  
  
  
  <field labelCode="code" class="col-sm-6 col-md-3">
    <input name="code" ngModel [readonly]="readOnly">
  </field>
  
  
  
  
</div>

Is there anyway these white spaces can be avoided. If we have to do it manually, it might kill the purpose of this code generator tool

Minimal Reproduction

Write a schematic template code with inline code <% inline code %>. Then build and generate code using commands

npm run build 
schematics .:ui-generator --name=hello

We can see generated code is having while spaces wherever inline code is present.
