Translations are missing the namespace prefix of Apps from Managed Packages

[amtrack]

Summary

When retrieving Translations from a Source-Tracked Org, the <customApplications> entries are missing the namespacePrefix of Apps from Managed Packages (e.g. Address Picker Autocomplete for Flow).

As a consequence the deployment of those invalid .translation-meta.xml files to another org fails with:

In field: name - no CustomApplication named Address_Picker_Autocomplete found

Steps To Reproduce

Please see my Git repository for all details and a reproduction using GitHub Actions: https://github.com/mdapi-issues/mre-translations-missing-namespace-of-applications

TL;DR

# create a Scratch Org with the Translation Workbench enabled
sf org create scratch -f config/project-scratch-def.json --alias translation-managed-application --set-default
# install the Managed Package "Address Picker Autocomplete for Flow"
sf package install --package 04t6F000004DJCEQA4 --no-prompt --wait 30
# deploy some unrelated translation of a managed CustomLabel
sf project deploy start --source-dir fixtures/some-unrelated-translation-of-a-managed-customlabel
# retrieve the translations from the Scratch Org
sf project retrieve start -m Translations
