Reset on Init fails when sensor in low-power state

[Cybot101]

Using an SAMD21 (Sparkfun Redboard Turbo) with SHTC3 via Quick/StemmaQT.
CP 6.0 beta.

shtc3_simpletest.py example works initially, but subsequent runs after soft-reboot will fail during SHTC3 init. Throws an OS Input/Output error from I2C write. Power cycle works again, until a soft-reset. Rinse, repeat. Possibly related to #1 (though not on rPi)?

Looking at the bus on a scope I can see the soft reset command 0x805D being NAK'd. The SHT address is ACK (so device is okay) but the write to registers is NAK.
I believe it is due to the sensor being put into low-power state after a read. When the soft-reset occurs the device is still asleep and ignores the request.

I have added a call to wake sensor before the soft reset and that appears to stop the error.

Can anyone else confirm similar behaviour? Maybe I'm missing something obvious? Can PR a fix if I'm on the right track.

simpletest.py code for reference

Sounds like you found a good fix for #1! A PR would be great. Thanks!
