First byte I2C decoding error in v 6.6.16.12

Hello,

I noticed, that I2C address gets decoded wrong if first bit follows start condition in short time.
Attached please find captured data and image containing correct interpretation of captured waveform.

Greetings, Darko

If you select Tools->SerialDecoding->Settings and change this to 8 bit read/write address it displays 70 as you would expect.
