Internal issue 3155 - Normalize.css is being injected at the root level of an app when using accordion

[ticket-sync]

Using the accordion component within a modal, when opening the modal a normalize.css file is being injected into the root level of the app and affecting styling of the entire app. Normalize.css is not being imported into the app manually and, as far as I can tell, it is being generated by the accordion.

Waiting for user response

Proposal: this needs more investigative work to find out if it affects other components.

Make a new small test app and introduce components individually, looking for the normalize.css issue.

Can't replicate. Asked user to help replicate it and they've confirmed they can't replicate it on our site or on Stackblitz, but the issue still occurs for their project. I've asked the user if they're using any other components to help narrow down whether it's just an accordion issue, waiting for their response.
