Weird one as devtools and cli works fine but the extension can't attach to it. @paulirish @brendankenny @patrickhulce anything special about drive.google.com for the extension?

https://photos.google.com/ and calendar worked just fine.

thanks very much for reporting. this is a top bug for us right now.

@wardpeet this originally comes from https://chromium-review.googlesource.com/c/chromium/src/+/1115203 but should be fixed by https://chromium-review.googlesource.com/c/chromium/src/+/1217599 in 70+
