UI bugs when using browser back button

There appear to be multiple bugs when a user uses the browser back button.

Example 1:

1. Go down a stem hierarchy with a few mouse clicks, hit the back button a couple of times, then click on a "Create Group" button.
2. The UI will want to create the group in the stem the user was in prior to hitting the back button.

Example 2:

1. Go to the group summary of a group.
2. Click on "View entity details".
3. Hit back on the browser.
4. Click "Delete" to delete the group.
5. The user gets an error.
