Cannot display the siteaccess menu when viewing a custom Landing Page.

Prereq.: Configure e.g. 4 siteaccesses.

Steps

1. Publish new Landing Page.
2. In Page part of the application change to a different siteaccess than site / default.
3. Add the LP name from step 1 to the URL in browser and hit Enter.
4. Try to change to a different siteaccess / click Page.

Actual: Siteaccess menu shows for a moment and hides (attached recording).
Expected: Siteaccess menu shows up and stays.

Remarks: Workaround is to go to Content / Content structure and then return to Page.
