pickerfun does not get called in cortex.webshow

[kroq-gar78]

Minimum reproducible example:

import cortex
volume = cortex.Volume.random(subject='S1', xfmname='fullhead')

def pickerfun(*args):
    print("picked:", args)

# create viewer
cortex.webgl.show(data=volume, port=1420, open_browser=True, autoclose=False, pickerfun=pickerfun)

import time
while True: time.sleep(0.5) # this is needed if running as a script

There is output in the web console, e.g.:

Picked vertex 95507 (orig 96465) in left hemisphere, voxel=[67,32,17]
Value on click: -0.12599994242191315

but there is none in the Python script.

I think commit 3595800 was supposed to have fixed this a long time ago, but it was dropped in a merge commit ( b9935a9 ) because it was on the legacy branch...

It would be great to fix this, I was thinking about some use cases recently for sanity checks/data checks. For example showing raw data timeseries when clicking on voxels, or displaying a map of correlations when clicking on a voxel (like instacorr in AFNI).
