ws2812.write only emits the reset signal on ESP32-C3 but not the data

Expected behavior
The ws2812.write function should emit the reset signal and the data.
Actual behavior
On the ESP32-C3 only the reset signal is generated. The data is not generated.
I could narrow down the problem to the function ws2812_fill_memory_encoded which writes new items to the RMT memory, but nothing appears on the outside. To be honest I have no idea what is going wrong, but I have a workaround. The new SDK offers a translator callback to generate new RMT items on the fly from input data. I have a patch for this.
Test code
This should burn a hole in your retina using the onboard RGB LED of the ESP32-C3-DevKitM-1:
