bokeh: [BUG] Cannot access `ColumnarDataSource`

This issue is potentially related to https://github.com/bokeh/bokeh/pull/11140

With Bokeh 2.3.1, 2.3.2, and 2.3.3 I see the following import error:

Uncaught ReferenceError: Cannot access 'ColumnarDataSource' before initialization
    at Module.eval [as ColumnarDataSource] (columnar_data_source.js?ffa7:1)
    at eval (cds_view.js?5c9c:13)

I did not see this error with 2.2.3.

This is my Webpack configuration:

      {
        test: /\.js?$/,
        include: /node_modules\/@bokeh/,
        use: [
          {
            loader: "babel-loader",
            options: {
              plugins: [
              "@babel/plugin-proposal-export-namespace-from",
              "@babel/plugin-proposal-optional-chaining",
              "@babel/plugin-proposal-nullish-coalescing-operator"
              ],
            },
          },
        ],
      },
