Description
I noticed that on the v0258 beta3 firmware from micro:bit v2.21the power led sometimes turns off when I press the reset button. So the device looks off, while it is actually still powered. This bug also concerns the Calliope mini V3 which uses DAPLink version 0258, and sometimes confuses users.

Research direction
Start by reproducing the power LED behavior on micro:bit v2.21 and Calliope mini V3 using v0258 beta3 firmware, pressing reset while battery-powered. Trace the firmware's reset and power-LED handling, then verify that the LED remains correctly lit after reset while the device is still powered.
