Subject: [PATCH] Python Chart Web: allow LocalContentCanAccessRemoteUrls
 (#4154)

new versions of qtwebengine block those requests by default

fix "Access to fetch at *** from origin 'file://' has been blocked by CORS policy:
   Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https."

see https://forum.qt.io/topic/132956/qwebengineview-javascript-fetch-cors-error-but-works-on-chrome-desktop
