May be fixed by #11906 in 0.21.0, but I have not tested yet.

I'm not able to reproduce this on master (9c4159a) on macOS 10.13.3.

@humphd Thanks! I have confirmed that this is fixed in the latest 0.21.x beta build (0.21.9).

Someone please close this, tag with the 0.21.x milestone, and add the release-notes/include label.

@bsclifton Could we include this in the 0.21.x milestone? Thanks.

@liunkae done- thanks for calling this out 😄 (fixed by @darkdh)

[bsclifton]

Moving to 0.22.x; we're going to have 0.21.x-C65 only contain the Chromium upgrade 😄 👍
