Property Value List Not Displaying On In-Page Editing

Description

Steps to reproduce

1. Create a block that has a list of strings and some other property.

[ContentType(DisplayName = "PropertyListBlock", GUID = "5474ff5f-da3a-4411-ad5f-0630a2d0b9e7", Description = "")]
    public class PropertyListBlock : BlockData
    {
        [CultureSpecific]
        [Display(
            Name = "Name",
            Description = "Name field's description",
            GroupName = SystemTabNames.Content,
            Order = 1)]
        public virtual string Name { get; set; }
 
        [CultureSpecific]
        [Display(
                    Name = "Property Value List",
                    Description = "Property Value List",
                    GroupName = SystemTabNames.Content,
                    Order = 10)]
        public virtual IList<string> ListOfStrings { get; set; }
    }

2. Add the block to e.g., the StandardPage in Alloy.

...
public virtual PropertyListBlock PropertyListTest { get; set; }
...

3. Render the property in the template.

...
@Html.PropertyFor(x=>x.CurrentPage.PropertyListTest)
...

4. Create a new page.
5. Add some values to the PropertyValueList in OPE.
6. Go to All Properties mode and look at the values.
7. Go back to OPE.
8. Open the PropertyValueList editor again.

Expected:
The values added in step 4 should be there

Actual:
The list is empty
