Research direction

Start by locating the injectCSS entry point and the styleNode.innerHTML assignment in the source or built output. Reproduce the Chrome-extension case on Gmail and inspect existing CSS-injection tests, if any. Done means CSS injection no longer throws the TrustedHTML error while preserving normal injection behavior.

Description

When trying to inject the Modal Component from antd design to Gmail page with a chrome extension, I have this error which broke the attempt.

But if I edit the built output to wrap a try / catch around the line of code that create the problem then everything go smoothly

try {
styleNode.innerHTML = css;
} catch {
}

I am confused, this is preventing me from making my chrome extension work on Gmail.
