WebIDE locks up while loading require("neopixel") on Nordic nRF52840 Dongle

Also, it is puzzling what the pin values should be.

From

https://github.com/espruino/Espruino/blob/master/boards/NRF52840DK.py

 'DEFINES += -DNEOPIXEL_SCK_PIN=22 -DNEOPIXEL_LRCK_PIN=23', # nRF52840 needs LRCK pin defined for neopixel

and

From:

Discontinous pin numbers (for nRF52840 dongle)
'Basically if all the pins are there then Espruino just works out the offset in pinInfo based on the number after D.'

I've been able to use digitalWrite() to confirm these four outputs that do toggle:

D2  :: 0.02
D29 :: 0.29
D31 :: 0.31

D13 :: 0.13

What should the designation be for pins such as 1.10 thru 1.16 ?

Can anyone provide a pin reference for one specific pin that does work on the Nordic Dongle using neopixels please.
