SpringBoot ErrorController should produce problem details if spring.mvc.problemdetails.enabled=true

Currently ErrorController will produce traditional error response even if problem details is enabled, nobody want to mix two different style of error handling.

    @RequestMapping("/")
    void home(HttpServletResponse response) throws IOException {
        response.sendError(HttpServletResponse.SC_BAD_REQUEST, "bad.request");
    }

    @Test
    void sendErrorShouldProduceProblemDetails() {
        ResponseEntity<Map<String, Object>> resp = testRestTemplate.exchange(RequestEntity.method(GET, "/").build(),
                new ParameterizedTypeReference<Map<String, Object>>() {
                });
        assertThat(resp.getBody()).containsKey("detail");
    }

Expecting actual:
  {"error"="Bad Request", "message"="bad.request", "path"="/", "status"=400, "timestamp"="2023-04-06T02:01:46.401+00:00"}
to contain key:
  "detail"

Here is minimal project problemdetails.zip
