    font-size: 36px;
}

Information about your Svelte project:

• All browsers

• Latest macOS

• Rollup

Severity
It took some time to realize this when trying to target elements that are inside the @html string. I then noticed that it is impossible in the first place without using :global but having a warning would be much much better.

Additional context
I can try fixing it myself.
