Description
After setting a Webcontent's Display Page to an 'Asset Display Page' its friendly URL can be immediately viewed while in the Guest 'Liferay' site, but if we tried the same thing in a non-default site, the Friendly URL is only valid after we view the 'Asset Display Page' via Asset Publisher.

Steps to Reproduce

1. Publish a valid Display Page with Web Content Article > Basic Web Content set as the Asset to be mapped
2. Create a Webcontent and set your Asset Display Page as the Display Page
3. Navigate to it

Expected Result
Navigation works both in Default 'Liferay' site and non-default site

Actual Result
Navigation only works in Default 'Liferay' site
