1 - Open or create a dialog that uses i18n and contains several fields. Enough fields so that you can scroll down on the dialog
2- Add multivalue or composite field at the bottom of dialog, add value for languages for those fields
3 - Scroll to the bottom of this dialog and focus on nested field
4 - Change languages

Note: rich text field has the same issue as described above.

Expected Result
The position that you were in on the dialog stays the same and does not move when you change languages. Nested field is also focused
