[chromium-dev] Blob support for Workers broken in Chrome 71 headless?

[Brian Di Palma]

We're using a Worker created via a Blob in our application.
This works in normal Chrome 71 but it's failing in Chrome 71 headless where
it worked in Chrome 70.
Specifically the message event listener callback is not being executed.
If we create the Worker via a script URL everything works as expected.
Is this an expect change or a bug?
I've tried to look through the release/commit log but I haven't found
anything obvious.

Does anyone have any relevant information about this issue?

Can you please file a bug, preferable with a minimal repro case? That makes
it easier to look into what is going on.
