Metamask-extension: EthQuery - RPC Error, stack trace included - Metamask 4.16.0

[roschler]

While using Metamask 4.16.0, it entered the state where it started queuing transactions instead of popping up the pop-up dialog, a problem that is mentioned in these related issues:

https://github.com/MetaMask/metamask-extension/issues/4006
https://github.com/OriginProtocol/origin/issues/386

In this occurrence I clicked on the Ubuntu Bionic Task manager and discovered an instance of the Metamask client window _that had gotten buried in the Z-order of the all the app windows_ I had open at the time (i.e. - it was underneath another app's windows, completely invisible). Being a typical developer I have quite a few at any time.

As a test, I clicked on the button in my dApp that triggers a Metamask session through a Web3JS call. When I did this, I got an alert box with the stack trace shown below (note, this stack trace also appeared in the Metamask pop-up so I was able to cut and paste it here):

It looks like some kind of a nested client instance issue but I'm just guessing of course. I hope this helps with your debugging efforts.
