Grid Export messages for dialog not working in developer mode

I am developing and running the composite project for an add-on and a full-stack application. In the add-on I am using a GridExport. When I run the application from the IDE, the messages in the Grid Export Dialog is not translated but when I build the application into a JAR and run it, the messages are being translated using the message bundle.

Why is this happening ?

Hello!

Could you clarify which Jmix version you are using? I tried to reproduce the issue in a simple scenario, but the problem did not occur. Could you share simple steps to reproduce the problem or provide a small demo project demonstrating the issue?
