short drag with zoom tool does not fire plotly_click

[arlowhite]

Sometimes, a user moves the mouse slightly during a click.
When the zoom tool is active, a short drag does not fire plotly_click, nor does zoom happen due to some minimum drag length for zoom. I've seen users frustrated by this behavior.
I think plotly_click should fire when there's a short drag under the min drag length.
The Pan tool seems to fire plotly_click for short drags.

This can be reproduced with the official demo: https://plot.ly/javascript/click-events/

In what contexts are you seeing this? We're probably not consistent about this, but at least the callers that go through dragElement get a minDrag that's usually set to 8px and should still emit a plotly_click below that threshold.

@alexcjohnson it's when the zoom tool is active
Try the official demo: https://plot.ly/javascript/click-events/
Drag a few pixels and nothing happens (except for gray background appearing during drag).
Switch to Pan tool, and small drag fires plotly_click

You're right, that should register a click. Thanks for clarifying!
We should probably make variants of all tests for all of our click events, where between mousedown and mouseup we add a small mousemove.
