Serial Monitor swallows my print lines

Any Serial.print*() command does not seem to make it to output when it is preceded by a log_X() command, with X= e, i, d, w, v. This simple script:

#include <Arduino.h>
#include <esp_log.h>

void setup() {
    Serial.begin(115200);
    Serial.println("setup started ###########################################################");

    log_i("%s",  "some text");
    log_i("%s",  "more text");
    log_i("%s",  "even more text");

    Serial.println("1");
    Serial.println("2");
    Serial.println("3");
    Serial.println("4");
    Serial.println("5");

    log_e("%s",  "but where are my numbers?");
}

void loop() {}

produces this output:

18:35:24.821 > setup started ###########################################################
18:35:24.821 > [I][main.cpp:8] setup(): some text
18:35:24.821 > [I][main.cpp:9] setup(): more text
18:35:24.821 > [I][main.cpp:10] setup(): even more text
18:35:24.821 > [E][main.cpp:18] setup(): but where are my numbers?

Yes, where are the numbers?

Okay then it seems to be in issue in their core. You should try and file a issue there to get the Serial and log_i() etc. functions / streams playing more nicely with each other.
