Parcel: Building a .html file strips "viewbox" property from SVG tags

[mathiasrw]

🐛 bug report

When "just" developing locally my SVG looks perfect. When I build the code the SVG gets all strange. It turns out that during build the property "viewbox" is removed from the

🎛 Configuration (.babelrc, package.json, cli command)

I use pretty plain parceljs so no babelrc.

.posthtmlrc looks like

{
  "plugins": {
    "posthtml-md": {
            "root": "src"
        }
  }
}

In parcel we have `"main": "dist/index.html",``

The command is parcel build src/index.html --no-source-maps

🤔 Expected Behavior

When having

<svg
    style="position: relative; top: 2px;"
    xmlns="http://www.w3.org/2000/svg"
    width="14"
    height="14"
    viewBox="0 0 24 24"
>
    <path
        fill="#af7d5c"
        d="M12 2c5.514 0 10 4.486 10 10s-4.486 10-10 10-10-4.486-10-10 4.486-10 10-10zm0-2c-6.627 0-12 5.373-12 12s5.373 12 12 12 12-5.373 12-12-5.373-12-12-12zm6 13h-5v5h-2v-5h-5v-2h5v-5h2v5h5v2z"
    ></path>
</svg>

in a file I expect the viewBox="0 0 24 24" to be part of the builded file.

😯 Current Behavior

The builded file does not contain viewBox="0 0 24 24" (prettified the minified output to make it easy to see)

<svg
    style="position: relative; top: 2px;"
    xmlns="http://www.w3.org/2000/svg"
    width="14"
    height="14"

    <path
        fill="#af7d5c"
        d="M12 2c5.514 0 10 4.486 10 10s-4.486 10-10 10S2 17.514 2 12 6.486 2 12 2zm0-2C5.373 0 0 5.373 0 12s5.373 12 12 12 12-5.373 12-12S18.627 0 12 0zm6 13h-5v5h-2v-5H6v-2h5V6h2v5h5v2z"
    />

svgo should only do this when the viewbox attribute isn't needed, but this should disable it nevertheless:

.htmlnanorc with

{ "minifySvg": { "plugins": [{ "removeViewBox": false }] } }
