Describe the issue

Dynamic URL filtering rule is not working as expected for worker requests in Firefox 52 / uBO 1.11.2; it does not take precedence over the dynamic filter as it should. I have the following rules:

* google.com * block
* https://www.google.com/recaptcha * noop

While most network connections to www.google.com/recaptcha are allowed as expected, the logger reports that connections of type worker ignore the noop and only listen to the block rule.

One or more specific URLs where the issue occurs

Here's an example. I even tried adding the allow rule below but the worker connection was still blocked according to the logger

gooligan.checkpoint.com https://www.google.com/recaptcha worker allow

Screenshot in which the issue can be seen

The first line below:

You can't see from this screenshot, but the two noop requests immediately under the worker (inline-script and frame) have the exact same URL as the worker request; could all three lines be referring to the same request?

Steps for anyone to reproduce the issue

1. Add the two rules near the top
2. Visit this URL with 1st party script enabled
3. Open the logger
