Infinite loop when turning on the hide from navigation menu from update engine

I have an infiinte loop on the closing of my page field engine when turning on the "hide from nav menu" on a live published page.

My current situation (on th eonline demo) is:

• The page "company" is in waiting for validation (never published)
• The sub-page "Communiqués" was published once
• the sister pages are also still waiting for validation

Then I updated the "communiqués" page and turn on the "hide from navigation" option. I saved.

Endeless loop on the "please wait" and the engine never close.
