As a developer, I like to address errors and warnings printed by build tools.

I maintain a project and recently upgraded to embroider/vite builds
Now, upon building I see the following error:

rendering chunks (4)...[esbuild css minify]
▲ [WARNING] Expected identifier but found "*" [css-syntax-error]

    <stdin>:444:2:
      444 │   *zoom: 1;
          ╵   ^

error cause and fix

I found that line comes from:

The CSS clearfix hack is quite old. I think those lines should be removed to fix it.
