Improper quote formatting in HubL functions inside of is_json=True block attributes.

[evelynn-causemic]

Description

When using a function or filter that takes a string inside of a JSON-formatted widget block attribute, all quotes are changed to double-quotes, terminating the string prematurely and causing the function to fail.

Expected behavior

A mixture of double quotes, single quotes, and escaped quotes would be used based on level of quote nesting.

To Reproduce

Original Source Code:
Here, the string passed into get_asset_url() is wrapped in single quotes, and the function resolves as expected.

{% widget_attribute "facebook" is_json=True %}
  {
    "custom_link_format": "", 
    "enabled": true, 
    "network": "facebook", 
    "img_src": "{{ get_asset_url('../images/icons/facebook.svg') }}"
  }
{% end_widget_attribute %}

Formatted Source Code:
After formatting, the single quotes are replaced with double quotes, setting the value of img_src to "{{ get_asset_url(".

{% widget_attribute "facebook"
            is_json=True %}{"custom_link_format": "", "enabled": true,
            "network": "facebook", "img_src": "{{ get_asset_url("../images/icons/facebook.svg") }}"}
{% end_widget_attribute %}

Additional context

These quotes are force-reformatted on every save, even if manually changed back. With current documented functionality, the only way to prevent this formatting is to prevent formatting for the entire document.
