wp-now: importFile step fails with error "DOMParser is not defined"

[squelchdesign]

I am running wp-now with:

wp-now start --reset --blueprint=blueprint-wp-now.json

My blueprint-wp-now.json:

{
    "landingPage": "\/wp-admin\/themes.php?page=squelch-tabs-and-accordions-shortcodes",
    "preferredVersions": {
        "php": "8.1",

        },
        {
            "step": "installPlugin",
            "pluginZipFile": {
                "resource": "wordpress.org\/plugins",
                "slug": "font-awesome"
            },
            "options": {
                "activate": true
            }
        },
        {
            "step": "installPlugin",
            "pluginZipFile": {
                "resource": "wordpress.org\/plugins",

            "options": {
                "activate": true
            }
        },
        {
            "step": "installPlugin",
            "pluginZipFile": {
                "resource": "wordpress.org\/plugins",

            },
            "options": {
                "activate": true
            }
        },
        {
            "step": "importFile",
            "file": {
                "resource": "url",
                "url": "https://github.com/squelchdesign/squelch-tabs-and-accordions-shortcodes/raw/oo-rewrite/sample-content.xml"
            }
        }
    ]
}

I get the following error:

The WXR import file isn't anything fancy, it only contains a single post with some sample content so as to provide a consistent testing environment for plugin development.

#113 looked to have the same issue — although they were using a different step action — but it's been closed as fixed.

I've also just noticed that I specified PHP8.1 but wp-now is actually running 8.0…?

Ah, #379 in wordpress-playground offers an explanation.

Feel free to close this as a duplicate if it's not helpful/needed.
