[Bug] Not highlighted Jinja2 syntax in HTML attributes

1. Summary

Jinja2 syntax not highlighted in attributes of HTML tags like in other places of HTML document.

2. Expected behavior

Part of my page.html file:

    <link rel="stylesheet" href="{{SITEURL}}/themes/sashapelican/statica/css/general/image_{{page.iconleftorright}}.css">
    <link rel="stylesheet" type="text/css" href="{{SITEURL}}/themes/sashapelican/statica/bower-components/rainbow/themes/css/rainbow.css">
    <!-- Открытие ссылок в новой вкладке -->
    <base target="_blank">
</head>

<body>
    <!-- Бэкграунд aside -->
    <aside class="sidebar" style="background-image: url({{SITEURL}}/themes/sashapelican/statica/images/aside/{{page.sashaicon}}.jpg)">
        <div class="cover">
            <div class="cover-text">
                <!-- Заголовок aside -->
                <h1>{{page.pagetitle}}</h1>
            </div>
        </div>
    </aside>
    <!-- Текст -->
    <main class="content-wrapper">
        <h1 class="SashaHeader">{{page.pagetitle}}</h1> {{page.content}}
    </main>
</body>

Expected

See {{page.pagetitle}} and {{page.content}}.

3. Actual behavior

See {{SITEURL}} and {{page.sashaicon}}.

Scopes for {{SITEURL}} and {{page.sashaicon}} It is the same as in the near text.

4. Steps to reproduce

The problem is reproduced for me in a version of Sublime Text without plugins and user settings.

I install Jinja2 via Package Control → I set Jinja2/Syntaxes/HTML (Jinja2) syntax for HTML files with Jinja2 templates → I open my page.html file → I get actual behavior.

5. Environment

Operating system and version: Windows 10 Enterprise LTSB 64-bit EN Sublime Text: Build 3126

Thanks.
