jquery page error

i try to open a web page that have a jquery chart, but webview don't plot the graphs.
i get the follow error:
I/chromium( 4451): [INFO:CONSOLE(2)] "Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.", source: https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js (2)

for example if you try to open this page in webview:
https://canvasjs.com/jquery-charts/spline-chart-export-image/
show the graphs empty

Start by reproducing the empty chart in the plugin's WebView with the CanvasJS jQuery example at https://canvasjs.com/jquery-charts/spline-chart-export-image/. Investigate the reported Chromium console warning and the WebView's handling of the page's chart resources; done means the example renders its graphs correctly in the plugin.
