ebay-line-chart: highcharts.js and accessibility.js are loaded in after the component mounts

Bug Report

eBayUI Version: 14.3.0

Description

Currently, if ebay-line-chart is loaded asynchronously, the component will mount and display an empty screen while it retrieves highcharts.js and accessibility.js. After those requests have been retrieved and run (self invoking), the chart will end up rendering as expected. The result is an awkward UX where the chart shifts layout after the necessary scripts are loaded in.

In order to load and initialize the scripts before the chart has loaded in, we should consider loading these resources before the component mounts. This could possibly be achieved through browser.json async loading.
