Hi,

I had the webmanifest working prefectly in Astro 3. I upgraded to Astro 4 and found the webmanifest does not work any more. There is always a residual .mjs file after a build. Besides astro-webmanifest, I am using @astro/sitemap and astro-robots-txt in my config. I was also generating an RSS feed using @astrojs/rss, which seems to have stopped working now. I am mentioning it to cover the off chance that it might be interacting with astro-webmanifest.

Cheers!
