Repro steps :

Create a blank page on a site, with at least one normal sub page.

Go in front-edition mode (you can just add "edition/" before the language in the url)

Click on the blank page link in the sitemap.

Expected : be redirected to the 1st sub-page and stay in edition mode.

Observed : we are redirected to the 1st sub-page, but we leave the edition mode.
