This issue is holding our upgrade up as well. Looking forward to getting the PR merged.

We temporarily work around this by replacing the document.contains string with document.body.contains using a webpack loader.

  module: {
    rules: [
      ...,
      // replace 'document.contains' with 'document.body.contains' for IE compatibility, util rc-align fixes it
      {
        test: /\.js$/,
        include: [path.resolve(__dirname, "node_modules/rc-align")],
        loader: "string-replace-loader",
        options: {
          search: "document.contains(",
          replace: "document.body.contains("
        }
      }
    ]
  }

Ah, thanks @zachguo that's great info. Hopefully the fix isn't too far away.
