<script> tag styling

[tillkruss]

We have JSON-LD script tags in our emails and they get a style attribute added to them, which doesn't make sense.

<script type="application/ld+json" style="font-family: Avenir, Helvetica, sans-serif; box-sizing: border-box;">
{
    "@context": "http://schema.org",
    "@type": "EmailMessage",
    "potentialAction": {
        "@type": "ConfirmAction",
        "name": "Approve Expense",
        "handler": {
            "@type": "HttpActionHandler",
            "url": "https://myexpenses.com/approve?expenseId=abc123"
        }
    },
    "description": "Approval request for John\u2019s $10.13 expense for office supplies"
}
            </script>
</body>
</html>

Could it be that you have a * {}-statement in your css file? Probably a reset-file.
Also, why using ld+json in emails? I don't think there is a mailclient that supports it.

Gmail does : https://developers.google.com/gmail/markup/

TrustPilot also requires this, see https://support.trustpilot.com/hc/en-us/articles/221618467-Add-a-structured-data-snippet-for-Automatic-Feedback-Service-#customer-name-and-reference-number-3

without a reproducer, there is nothing we can do.

But I indeed suspect that the answer of @tijsverkoyen is right: having a style rule that matches *, and so applies to this script element as well.
