imported module not found in class in Pyodide

I am trying to use pyodide with lxml and urllib3, for some reasons I don't understand, when I try to use urllib3 in a class supposed to be a Resolver for lxml etree I get an error NameError: name 'urllib3' is not defined.

Example code is online at https://martin-honnen.github.io/pyodide-tests/simple-requests-test-case3.html (note that all output goes to the browser console so use F12 to see the output).

Code is doing <script src="https://cdn.jsdelivr.net/pyodide/v0.26.0/full/pyodide.js"></script> and then

    const python = `
import js

import urllib3

import lxml

from lxml import etree as ET

url = base_url + 'foo-transform-module.xsl'

js.console.log(urllib3.request('GET', url).status)

class TestResolver(ET.Resolver):
    def resolve(self, url, id, context):
        print("Resolving URL '%s'" % url)
        if url.startswith('http'):
            return self.resolve_file(urllib3.request('GET', url), context)
        else:
            return False


parser = ET.XMLParser(no_network=False)
parser.resolvers.add(TestResolver())

tree = ET.parse(url, parser)

tree.getroot().tag
  `;

    async function main() {
        let pyodide = await loadPyodide();

        await pyodide.loadPackagesFromImports(python);

        const locals = new Map();
        locals.set('base_url', window.location.href.replace(/[^/]+?$/, ''));

        console.log(await pyodide.runPythonAsync(python, { locals : locals }));
    };

    main();

Full error in console is

Is there some flaw in my code? How do I get the imported module to be known in the code of the class?

I deleted old answer because it was wrong.

It seems all problem makes locals - maybe it removes original urllib3

I found Pyoide FAQ: How can I execute code in a custom namespace?.
It shows some examples with globals.

It seems this works for me:

let my_namespace = pyodide.toPy({'base_url': window.location.href.replace(/[^/]+?$/, '')});
    
await pyodide.runPythonAsync(python, {globals: my_namespace});

Information for other users: problem was send by OP to Pyodide as issue
