Bug description

Missing CSS resources

Steps to reproduce

Install these apps

Access the tasks app

Expected behavior

No console errors.

Got this error:

Refused to apply style from ... custom_apps ... because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

However this is actually just an error that that file does not exist.

Reproduced, but this doesn't look to be a server matter. The mime type mismatches are just due to those css resources not being found, so the 404 filler is taking their place (which will havetext/html mime type so it'll violate the security policy since text/css was expected). EDIT: Though I guess there could be an interaction with the apps_path config, but given other apps don't have this problem - as far as I can tell - I find this unlikely.

Just looks like the tasks app might need some clean-up somewhere. I'll move this over there.

Indeed, vite exported the CSS chunks a little differently now, which means we don't have to include them separately anymore, but only the main chunk. I will create a fix for this.
