inlineStyleThreshold: Infinity not escaping ` in css file #15319
Description
Describe the bug
Bug encountered after build and attempting to deploy
Any inlineStyleThreshold: Infinity fulfilling the prerequisites will end up having trouble deploying because of this bug where it is impossible for SSR to serve page because css inlining encounters an error (in my case, using wrangler preview)
Reproduction
Make a simple css file with ` in it. Usually something like this:
.sample:after {
content: '`'
}add other css that requires dynamic linking, usually a font css declaration, in order to make the build file make something like this:
export default function css(assets, base) { return
attempt build
