Other information:
No change file because there hasn't been a release since the last commit that changed this behavior. (e3e2e39)

An alternative solution would to be implement a struct JsStringLiteral with a fmt::Display that escapes all forbidden codepoints detailed in the spec: https://www.ecma-international.org/ecma-262/#sec-literals-string-literals
An approach very similar to this was previously used to escape css content injected inside of the webview crate. (the one before webview_official)

Template string literal fix seems to be by far the simplest change to fix it. All browsers that tauri supports (the webview browsers) have had support for them for the past 3-4+ years.

I didn't catch this during e3e2e39 because my css was minified with no newlines.

alternative solution would to be implement a struct `JsStringLiteral`
with `fmt::Display` that escapes all forbidden codepoints from the spec
https://www.ecma-international.org/ecma-262/#sec-literals-string-literals

template string literal seems fine as all browsers that tauri supports have
had support for them for the past 3-4+ years
