Research direction

Start by reproducing the issue on the Plotly lasso-selection example at https://plotly.com/javascript/lasso-selection/ with the browser devtools open. Select a range, adjust it, and compare the behavior in the referenced Plotly versions. Done means adjusting an existing box or lasso selection no longer produces infinite logs or freezes the page.
