`block-lang` triggers on non-svelte files

[marekdedic]

Hi
block-lang reports plain .ts files as well, no just svelte files - kind of a false positive.

I'll try to fix it, but I am not sure how to find out whether a file is a svelte file - @ota-meshi, do you just check for file extension? I can't check for <script> or <style> blocks as they theoretically may not be present...

Thank you for your bug report.

I think we might get around the problem by adding a guard like this:

     if (!context.parserServices.isSvelte) {
       return {}
     }
