Describe the bug / provide steps to reproduce it

Problem Description
When using ZED with a Django project, saving a template file like the following:

{% extends "base.html" %} 
{% block title %} Certificate List {% endblock %}
{% block content %}
<select name="consignatario__pais" id="consignatario__pais" class="form-control select2" required style="width: 100%">
    <option value="">Select a country</option>
    {% for pais in paises %}
    <option value="{{ pais.id }}" {% if consignatario_pais == pais %} selected {% endif %}>{{ pais.nombre }}</option>
    {% endfor %}
</select>
{% endblock %}

Results in the following unwanted transformation after saving:

{% extends "base.html" %}
{% block title %} Certificate List {% endblock %}
{% block content %}
<select
    name="consignatario__pais"
    id="consignatario__pais"
    class="form-control select2"
    required
    style="width: 100%"
>
    <option value="">Select a country</option>
    {% for pais in paises %}
    <option
        value="{{ pais.id }}"
        {%
        if
        consignatario_pais=""
        ="pais"
        %}
        selected
        {%
        endif
        %}
    >
        {{ pais.nombre }}
    </option>
    {% endfor %}
</select>
{% endblock %}

Impact of the Issue
The {% if consignatario_pais == pais %} statement is rewritten incorrectly, introducing errors and breaking the template logic.
Additionally, unnecessary line breaks are added, which breaks the django template system, and of course also impact readability and code maintainability.

Additional Details
Uninstalling the responsible extension (HTML) solves the problem only temporarily, as it is automatically reinstalled when restarting ZED. Should this behavior be reported as a separate bug, or is it part of the same issue?

Steps to Reproduce

1. Open a Django project in ZED.
2. Edit a template file like the provided example.
3. Save the changes.
4. Observe how the code is automatically transformed.
5. Undo the changes
6. Uninstall HTML extension
7. Save again (now there are no modifications)
8. Close the app, restart the computer (I'm not 100% sure this part happens every time you restart the computer)
9. The HTML extension is installed again

It sounds like you want to disable Prettier's formatting for HTML:

{
  "languages": {
    "HTML": {
      "prettier": { "allowed": false }
    }
  }
}

Going to close this out, as the setting above should put you into the proper state to avoid formatting on save in HTML files.
