Seems that names/labels in localization message files are case insensitive in Chrome and Firefox, but not in Orion. If extension developer mixed up the cases of labels in code and message files, some translations are missing in Orion.
https://developer.chrome.com/docs/extensions/mv3/i18n-messages/
Steps to reproduce:
Install any extension and look for missing translations.
Expected behavior:
Names in localization message files should be handled/loaded case insensitive.
