Changes might be lost on objects when refreshing

Reproduction steps:

• Create a page with a stylesheet xobject containing something like:

  .content {
      color: red;
  }
  

• Edit the object to change red to black and save the change in a new change request
• Return to the page and delete the xobject
• Return to the change request

Expected result:

• the CR should display a conflict and the default resolution should be to keep the xobject with the provided changes

Obtained result:

• the CR doesn't display a conflict but only proposes to refresh the changes, which lead to entirely loosing all changes
