Display Language doesn't update automatically

[rebornix]

• Open argv file and change the display language.
• No restart notification is shown

Re #93771

• Change Display Language in one instance, it requires restarting the app
• The second instance doesn't show any notification after sync update
• Restart the second instance uses the new display language

Yeah there is no notification when display language is changed in the source file. Its not just by sync also if you open the file and change it.
