Reproduced on:
Tomcat 9.0.10 + MySQL 5.7. Portal master GIT ID: 19bbbf1ad18eff190403f1c452b1ece9eadf2ddd.

Steps to reproduce:

1. Navigate to Build > Pages > Display Pages (or Page Templates)
2. Create a display page or standard page template

Expected result:
There is a back button.

Actual result:
There is no back button so there is no easy way for the user to return to display pages administration (or page templates administration) other than to use the browser back button. This becomes more problematic after publishing, meaning the user has to click back in the browser multiple times.
