Description:

1. Log into the portal with default Test admin. Go to Control Panel, Sites. Add a new blank site, save.
2. Go to the Pages section and add 1 pages: a1.
3. Select a1 page and add a child page: a11. (a1 will be opened and show a11)
4. Close the opened node a1.
5. For reproducing this bug we need to delete user session. (LPS-48480 will fix that)
6. Try to open a1.

Actual behavior: a1 will be opened but child node(a11) isn't displayed.

Expected behavior: a1 will be opened and child node(a11) will appear.
