OpenOCD breakpoint followed by step does NOT disable _xt_lowin1 IRQ

[FrancoisB-HEX]

I am trying to step though code on an ESP32S3 running ESP-IDF release v5.5.1 after hitting a breakpoint (JTAG built-in USB), but I am getting _xt_lowint1 IRQ calling FreeRTOS SysTickIsrHandler before the next line of code is even hit.

Is this simply a result of https://docs.espressif.com/projects/esp ... tine-calls, or am I correct in expecting OpenOCD to disable IRQs and watchdogs when debugging?
If it is not done by default but it possible, how can I disable _xt_lowint1 (and other IRQs) when debug stepping through code?
