[electron] Missing content in debug view

[mark-edgeworth]

When I run the UI in electron and attempt to debug some JS the Variables and Breakpoints sections of the debug pane are empty.

However, when I run the backend (using Launch Backend) and connect using a browser the variables and breakpoints sections of the debug view are filled-in correctly.

Run with master as of this morning.

To be clear, I did add a single breakpoint and theia was correctly stopped at it.

@mark-edgeworth Hi 👋

Can you check please your backend logs? Do you see something like here: #3408 (comment)

[akosyakov]

I was able to reproduce it, it does not seem to be related to #3408

The fundamental issue that we use runtime features from es5 which are not supported in Node.js version bundled with Electron 1.8.2. I would prefer that we move to the latest stable Electron.

@mark-edgeworth Could someone from ARM to have a look at #3693?

@akosyakov We are keen to bump up the electron version. Let me investigate the work needed.

@thegecko there can be a bit more work, in addition, to bumping up the electron version :) related to nsfw package @kittaakos should know better

This should be fixed when the Array.values() usages are removed as part of #3730 .
