Razor RenderPartial generates wrong HTML - razor

Question

I have a page Item Edit with multiple partial rendered forms for images delete. Item Edit page:
#model EditModel
<form method="post" enctype="multipart/form-data">
<input asp-for="ItemModel.Id" type="hidden" />
<input asp-for="ItemModel.AllOtherFields" type="hidden" />
</form>
#if (Model.ItemModel.ImageViewModels != null && Model.ItemModel.ImageViewModels.Any())
{
foreach(var imageViewModel in Model.ItemModel.ImageViewModels)
{
Html.RenderPartial("ItemImage/_itemImageEdit", imageViewModel);
}
}
ItemImage/_itemImageEdit
#model ViewModels.ItemImageViewModel
<form asp-controller="Images" asp-action="Delete" method="post">
<input type="hidden" asp-for="#Model.Id" />
<img src="#Url.Action("Get", "Images", new { id = Model.Id })" />
<input type="submit" value="Delete" />
</form>
and here is my strange final html
<form method="post" action="/Images/Delete/5" novalidate="novalidate">
<input type="hidden" data-val="true" data-val-required="The Id field is required." id="Id" name="Id" value="5">
<img src="/Images/Get/10">
<input type="submit" value="Delete">
</form>
Where 5- Item id and 10 - image Id. So this is expected and correct
<img src="/Images/Get/10">
while this is not. Item Id used instead of id (ItemImageViewModel.id)
action="/Images/Delete/5"
I have no idea why does #Model.Idgenerate different ids on the same subview.
Edit1:
public class ItemImageViewModel
{
[BindProperty]
public int Id { get; set; }
public string Title { get; set; }
public int ItemId { get; set; }
}
public class ItemViewModel
{
public ItemViewModel()
{
}
public ItemViewModel(ItemViewModel vm)
{
Id = vm.Id;
Title = vm.Title;
ImageViewModels = vm.ImageViewModels;
}
public int Id { get; set; }
public string Title { get; set; }
public IEnumerable<ItemImageViewModel> ImageViewModels { get; set; }
}
I have removed unrelated fields.
Debugger shows alright

Now this weird piece of code generates what it supposed to generate
<form action="#Url.Action("Delete", "Images", new { id = Model.Id })" method="post">
<input type="hidden" id="Id" name="Id" value="#Html.DisplayFor(m => Model.Id)" />
#Html.HiddenFor(m => Model.ItemId)"
<img src="#Url.Action("Get", "Images", new { id = Model.Id })" />
<input type="text" asp-for="#Model.Title" />
<input type="submit" value="Delete" />
</form>
<form action="/Images/Delete/10" method="post" novalidate="novalidate">
<input type="hidden" id="Id" name="Id" value="10">
<input data-val="true" data-val-required="The ItemId field is required." id="ItemId" name="ItemId" type="hidden" value="5">"
<img src="/Images/Get/10">
<input type="text" id="Title" name="Title" value="Jacket">
<input type="submit" value="Delete">
</form>
