OData endpoints with "search" in the route don't work

Any OData endpoint with "search" as the final URL segment returns 404 upon making any request.

An action such as this returns 404:

[EnableQuery]
[ODataAttributeRouting]
[HttpGet("~/api/odata/search")]
public IActionResult OData() {
    // return dataset
}

Other routes such as ~/api/odata/searc, ~/api/odata/testsearch, or ~/api/odata/search/test all work as expected, this only occurs when "search" is the final URL segment.

EDIT:

After some further investigation this appears to be related to the name of the entity set. When the entity set is added with the name all lowercase, the endpoint works as expected. If the first letter of the name is capitalised, the route does not work.

builder.EntitySet<Search>("Search"); // doesn't work
builder.EntitySet<Search>("search"); // works

I have not seen this behaviour with other entity sets, they work regardless of the name case.
