.editorconfig not respecting object initializer rule

Version Used: Visual Studio 16.1.4

Steps to Reproduce:

I have my .editorconfig set up for my project, and it mostly works well, but I've seen a problem where it doesn't seem to recognize my object initializer preference. This feels similar to #30529, but I'm still having the problem even though that was marked as resolved.

In my .editorconfig, I have the following settings (among more, which I can post if needed to see if there's something else overriding it):

csharp_new_line_before_open_brace = all
csharp_new_line_before_members_in_object_initializers = true

Expected Behavior:

I want my object intialization to look like this:

var obj = new MyObject
{
    Prop1 = 7373,
    Prop2 = "Hello world",
};

Actual Behavior:

When I run the code cleanup, it reformats the object initialization to:

var obj = new MyObject {
    Prop1 = 7373,
    Prop2 = "Hello world",
};
