I had hoped that I could build a webapp and embed all the templates using //go:embed, parse them all into one template.Template instance, and then later use ExecuteTemplate on that to render the right template for each page. However, I can't seem to make that work, I get the wrong template executed no matter what order I load the templates in, and whether I use ParseFiles, ParseFS, or ParseGlob.

Anyone know why? Do I need a separate template.Template instance for each page?
