LPS-43967 - DDL - Iframe remains open after clicking to Add a translation to a Record

Hi @jonmak08,

Attached is an update for https://issues.liferay.com/browse/LPS-43967.

I made the changes you recommended in https://github.com/jonmak08/liferay-portal/pull/689.

But I was unable to reproduce the issue with the translations not saving when being published.  

Please let me know if there are any issues.

Thanks!
