out of tree build fails: "'_DefaultIsolatedEnv' object has no attribute '_scripts_dir'"

🐛 Bug

I am trying to do an "out of tree build" of the package aioesphomeapi.
I followed the procedure outlined in the docs.
At the step to build (pyodide build) I get the following error:

✗ pyodide build                                                    
xbuild environment already exists, skipping download

Traceback (most recent call last):
  File "/home/kaktus42/miniconda3/lib/python3.10/site-packages/pyodide_build/pypabuild.py", line 71, in _runner
    env["BUILD_ENV_SCRIPTS_DIR"] = isolated_build_env._scripts_dir
AttributeError: '_DefaultIsolatedEnv' object has no attribute '_scripts_dir'

ERROR Backend operation failed: AttributeError("'_DefaultIsolatedEnv' object has no attribute '_scripts_dir'")

The "normal" build (python -m build) works without problems.

To Reproduce

Just running the build as described.

Expected behavior

Successful build.

Additional context

This will be fixed by #4653 (we will release pyodide-build 0.25.1 soon with that patch). For pyodide-build 0.25.0, downgrading the build version:

pip install build<1.2.0

will resolve the issue.
