 Description

When translating the Forms for a locale different than English US, the Custom Required Error Message doesn't display the translation of the default error message on the sidebar, but when the Form is published the proper translation is displayed.

 Steps to Reproduce

1. Go to Content & Data >  Forms > Create new Form
2. Add any field
3. Toggle the Required Field switch
4. Add translations for another locale but don't translate the required error message
5. Publish the form and open it
6. Change the language for the translated locale and trigger the required error message 

 Expected Result
The value of the required error message should be displayed on the sidebar property so it doesn't lead the user to expect there's no translation for the default required error message.

 Actual Result
The value of the required error message is displayed in english on the sidebar property for any translated locale, but is translated when Form is published.
