Description

It seems that geom_step is truncating the line too early when it encounters a null value. Rather than continue the line until the null value, it stops at the prior value:

Example:
ggplot(data.frame(x=1:5, y=c(1,2,NA,1,1)), aes(x,y)) + geom_step()

Plain ggplot2:
ggplot

Plotly:
plotly

Research direction

Start with the geom_step implementation and its handling of null or NA values, using the issue's R example to reproduce the discrepancy. Compare the Plotly output with plain ggplot2 and verify that the step line remains extended through the value before NA rather than ending prematurely.
