COMPOSER_HOME is overidden, why? This causes the global composer configuration to be ignoring resulting in errors.

Hi,

We receive an error (see error below) when running either composer update or composer scenario:update. This happens because the COMPOSER_HOME environment is set to the working directory each time update:lock is executed for each scenario. (See Handler::298.)

We have defined an auth.json in the original composer home directory which is required to access our private package registry (managed by our own GitLab instance). This file is not available in the working directory.

Simply commenting putenv("COMPOSER_HOME=$dir"); resolves the issue. Why is the original home directory changed before update:lock is executed?

The error:
