Description
This was introduced some time between 2018-01-26 to 2018-03-07
df <- data.frame(x = runif(10000, min = 0, max = 20000), y = runif(10000, min = 0, max = 20000))
plot_ly(df, x = ~x, y= ~y) %>% add_markers() %>% toWebGL()
When the above code is run with plotly from 2018-01-26, selecting points works fine. But when run with a version from 2018-03-07, selecting points causes them to jump.

Research direction
Start by running the provided R reproduction with plotly.R versions from 2018-01-26 and 2018-03-07, then compare the WebGL selection behavior and inspect the regression between those versions. Done means selecting points in the 10,000-point plot no longer makes them jump.
