Possible bug with core_v2_role.List() in 12.1.4

It looks like there is an issue with core_v2_role.List(), and maybe the REST variant as well (I didn't test).

I ran this in the Script Sandbox

let page = core_v2_role.List({ PageIndex: 0, PageSize: 10 });

return [
    'page.PageIndex=' + page.PageIndex, 
    'page.PageSize=' + page.PageSize,
    'page.TotalCount=' + page.TotalCount,
].join('<br>');

===== OUTPUT =====
page.PageIndex=0
page.PageSize=0
page.TotalCount=0

There are dozens of results returned, but the PageIndex, PageSize, and TotalCount were all 0.

If I call it the method with some arguments I get different results.

let userId = core_v2_user.Accessing.Id;
let page = core_v2_role.List({ Include: 'user', PageIndex: 0, PageSize: 5, UserId: userId });

return [
    'page.PageIndex=' + page.PageIndex, 
    'page.PageSize=' + page.PageSize,
    'page.TotalCount=' + page.TotalCount,
].join('<br>');

===== OUTPUT =====
page.PageIndex=5
page.PageSize=0
page.TotalCount=10

The TotalCount is correct, but the values for PageSize and PageIndex in the result object have been reversed.

I can work around this, but wanted to mention it.

The full version is: 12.1.4.25258
