I am trying to create a web component from a svelte project that uses the svelvet component library. I am using <svelte:options tag=”my-element” /> in my App.svelte file and set customElement: true in my rollup config file for generating the web component. When I build and run my project, I don’t see anything displayed and the browser console displays the error “Uncaught TypeError: Illegal constructor”. What else could be causing this issue?
