mobile Twitter peculiarities with Block Service Workers

[grahamperrin]

Block Service Workers 1.0.0, Chromium 72.0.3626.121 (Official Build) (64-bit) on FreeBSD-CURRENT.

tl;dr at https://mobile.twitter.com/settings/push_notifications after I click NO to block, I get none of these things:

1. a block
2. the service worker at chrome://serviceworker-internals
3. push notification preferences at https://mobile.twitter.com/settings/push_notifications

If, instead, I click YES to allow then there's an apparent allowance but still, non-appearance of preferences:

I waited a long time for preferences to appear, they didn't.

Quit, relaunched Chromium: no difference (still non-appearance of preferences within the Twitter window).

A few seconds after I disabled the extension, preferences appeared:

– and I gained a worker for mobile Twitter.

Sorry of the late reply.
I was able to reproduce it, yes. Unsure what would cause that, I'd need to dig into it.
As a workaround, like you mentioned, choose 'ALLOW', disable the extension, reload the page and finally re-enable the extension.
