Chrome Version: 72.0.3626.53, 73.0.3643.0, 73.0.3667.2
OS: Android 9 on Pixel, and ChromeOS on Pixelbook (the device with devtools open)

What steps will reproduce the problem?
(1) open test page on Android device: mdn.github.io/simple-web-worker
(2) test page functions (and logs) correctly
(3) plug Android device into Pixelbook and inspect via devtools
(4) reload the same test page

What is the expected result?

test page would function as normal. web worker would print its logs.

What happens instead?

test page does not function correctly. web worker does not run (doesn't log, doesn't show up in sources tab, but DOES show up in network tab). so it seems the Worker is constructed, but never executes its code.

note that everything works fine in Chrome Stable on Android (71.0.3578.99), so I'm only seeing this issue in >= 72.0.3626.53

let me know if I can provide any additional info
