Reproducible using Mbed Studio and mbed-os-example-blinky on Mbed-LPC1768 board. Started with a device with blank flash.
This is not caused by the device entering sleep mode. I had completely disabled calls to hal_sleep() or hal_deepsleep() in sleep_manager_sleep_auto() before running this test.
Selected port 50000 for debugging
