Description

I came across this "bug" in a comment on stackoverflow while I was trying to get addTrace working.

https://stackoverflow.com/questions/50620360/using-proxy-interface-in-plotly-shiny-to-dynamically-change-data

I can comfirm that this seems to be the case. addTrace should work even with 0 points in the trace I think, since you might want to add point later.

Research direction

Start by reproducing the reported behavior through plotlyProxy() and addTrace, using the linked Stack Overflow example as context. Trace how an empty trace is type-checked and verify that adding a trace with zero points succeeds while still allowing points to be added later.
