i have a simple index.html with an import of a component, exaclty this. On Chrome works fine, but on others browser (i tried firefox and safari) not, it shows only the index.html content, not the template content of the component. I read this and it seems like my situation, but this solution doesn't work for me.
EDIT: imports are correct (from IDE, if I command+click on links, I can go to the .js)
