Unterminated string literal error in @vincjo/datatables

[ritikdubeyEn]

Describe the bug

When using @vincjo/datatables with a Svelte 5 project, several files in the package throw an "Unterminated string literal" error during build. These errors seem to occur in multiple .svelte files from the library. Opened a thread on vincjo issues, but seems to be issue is not there. vincjo/datatables#153 Also issue seems to be reported here in Mitcheljager/svelte-confetti#18

Reproduction

Create a new Svelte project:

npm create svelte@latest my-svelte-app
cd my-svelte-app
npm install

Install @vincjo/datatables:

npm install @vincjo/datatables
Import and use any component from the library in a .svelte file.
Run the project:

npm run dev

Can you confirm that the issue persists with 5.18.0? There has been a similar issue that was just fixed (esrap not properly serializing strings)
