Nothing is displayed for 'Arduino Board Configuration'

[brndmg]

When I run the 'Arduino Board Configuration' from the ctrl-shift-p or by clicking the board name in the footer, the tab opens with the title but there isn't any content.

The following error is shown in the Developer console.

[Embedded Page] Uncaught Invariant Violation: Element type is invalid: expected a string 
(for built-in components) or a class/function (for composite components) but got: object. 
Check the render method of `BoardConfigItemView`. [webview.ts:151]

I should mention that I am running Ubuntu 16.04.
Arduino IDE 1.8.4

I have a working fix for this, I will be submitting a PR shortly.

Can confirm on Win10 with exact same error.

Arduino 1.8.4
Arduino AVR boards 1.6.19

Arduino AVR boards 1.6.20 is out, but I am not using it because it gives me this error:

/opt/arduino-1.8.4/hardware/tools/avr/bin/avr-gcc-ar: Cannot find plugin 'liblto_plugin.so'

The Arduino editor with AVR 1.6.19 works fine. VSCode with this Arduino extension does not show the Arduino boards select dropdown.
