LEDC unable to attain 100% duty at 120Hz; no pulse at 60Hz?

I have generated a LEDC PWM output at 120Hz and faded between 0 and 1 * (1 << LEDC_TIMER_19_BIT). During the fade period a separate task polled ledc_get_duty() and reported values that basically made sense. However on the oscilliscope it seemed the pulse grew from zero to around 2/3rds, instead of a...
