Steps to reproduce:

1. Add Language Selector portlet
2. Switch to Hebrew (Israel)
3. Sign out
4. Sign in

Expected Result: When the product menu is expanded, it's right-justified and portal spans the rest of the window.

Actual Result: When the product menu is expanded, portal only spans the middle of the window and there's an empty space where the left-justified product menu would be.

Reproduced on:
Tomcat 8.0.32 + MySQL 5.7.20
