How to stop Edge from automatically downloading source mapped UI5 library files (*-dbg.js)?


Opening up the developer menu (F12) in Edge instantly triggers Edge to start downloading all source map files. I mean all, all individual js files e.g. sap/m/Button-dbg.js.

It freezes up the browser and makes it impossible to do performance network tracing using the built in developer tools.

How can I stop this from doing that automatically?

Steps to reproduce:

  1. Open MS Edge
  2. Browse to https://sapui5.hana.ondemand.com/test-resources/sap/m/demokit/orderbrowser/webapp/test/mockServer.html
  3. Once the webpage is completely loaded, press F12
  4. You now notice it starts downloading all source map files for the UI5 framework (*-dbg.js)
