[BethGriggs]

• Node Version: multiple
• CitGM Version: 7.0.0
• Platform: multiple

through2 appears to be failing on many platforms across all release lines with the following error:

I suspect it's linked to rvagg/through2@164d3f8 and we probably want to avoid the test:browser script for Node.js.
