Stylus 2.0.0 cannot import styles

LoraFriedenthal

Stylus 1.5.51 is able to import and use styles.
Stylus 2.0.0 is not. The Stylus team thinks your implementation of importScripts is broken

In 2.0.0 the CSS file doesn't import and will not apply to a website.

Install Stylus 2.0.0 plugin from Chrome store
Go to https://userstyles.world/style/4773/mastodon-modern
Click on Install
You will see an error that it cannot find metaParser

To see the expected functionality, install Stylus 1.5.51 from the attached zip file.

My guess so far is that importScripts is broken inside SharedWorker of a chrome extension.

From the Stylus devs.

Still seems to be broken, but in additional ways from the original post. I can't even manage to get into the settings UI for the Chrome extension, the Firefox version does load the settings page just fine.

Importing Settings

Importing settings, either normal or from a 'compatibility' export, both fail to import UI or console errors.

Cloud Syncing

I tried to work around this by using cloud syncing but neither Dropbox nor OneDrive work.

The Dropbox window goes blank at some point and doesn't load anything, it's just a blank page.

I get the following (odd) console error:

Failed to load resource: the server responded with a status of 404 (Not Found)
https://www.dropbox.com/favicon.ico

OneDrive gets most of the way through but stalls at Trying to sign you in and throws the following console error:

Failed to load resource: the server responded with a status of 404 () 
https://aadcdn.msftauth.net/shared/1.0/content/js/oneDs_{guid that might be an unique token}.js.map

Both Dropbox and OneDrive need their authentication window closed and Stylus reports Canceled by user. No additional errors in the console.

Importing Styles

Okay, well, if I can't import my settings I should be able to rebuild my configuration, right?

Loaded up my first style on UserStyles.world and hit Install. I get an nice spinner that never completes. Console throws the following six times:

TypeError: undefined is not an object (evaluating 'window.webkit.messageHandlers')
(anonymous function) — user-script:319:9

Pasting Styles

Going even more manual, I create a new CSS snippet in the options and try to paste the code in.

When I create a new style I see the following console error:

Unhandled Promise Rejection: ReferenceError: Can't find variable: CSSLint
(anonymous function) |
enqueueJob

I tried to paste the CSS in and Stylus recognizes that I'm pasting in Mozilla-format code and displays it in a modal. Hit Overwrite style and while I don't get a console error Stylus shows Failed to import from Mozilla format, Load failed.

Pasting it in line by line doesn't prompt the modal, but when I tried to save it it doesn't do anything.

This extension seems to be completely incompatible with Orion.

1.5.51 is still the last working version of stylus for orion as of now, all new versions give the same errors.

1.5.51 is working on macOS but not on iOS for some reason:

There the settings page doesn't manage to load the input element state as it should (i.e. it will not check checkboxes which are checked per default, and the close (aka. save) button does nothing, it stays open.

While importing an existing config from file works, actually using the styles does not seem to work.
Website styles are not loading and/or not able to apply CSP fixes — not quite sure yet as the page I tried to get my css working on was heavily CSP protected.

I also tried xStyle, FireMonkey and Stylus.
