On xpages, the container of a component with a running experiment is not locked

Problem

Steps to reproduce:

1. Go to a channel
2. Open an xpage
3. Add a component and create 2 variants for it
4. Create an experiment (select a goal on the Experiment tab and Save) 
5. Publish the page to start the experiment

Expected result:

• Container of the component is locked
• (As a result) Nothing on the Properties tab for the component is editable: neither variants nor properties

Actual result:

• Container is unlocked
• (As a  result) Properties and variants are editable

Resolution

On xpages (like on hst pages) lock containers that have a component with a running experiment. Ideally, the container should already be locked on creating the experiment.
