report-uri / report-to rejector RegExp is broken

[jspenguin2017]

Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

$csp= does not allow report-uri nor report-to, however, the RegExp rejecting these directives are broken.

A specific URL where the issue occurs

N/A

Steps to Reproduce

1. To go My filters
2. Add ||example.com^$csp=report-to https://other.example.com;

Expected behavior:

The filter is rejected

Actual behavior:

The filter is accepted. The current RegExp looks like this: /(?:^|;)\s*report-(?:to|uri)\b/

The option tested against the RegExp above is like csp=..., so the Start of line would cause it to never match when report-... directive is at the beginning.

Your environment

• uBlock Origin version: 1.23.0
• Browser Name and version: Chrome 80
• Operating System and version: Windows 10

Maybe change it to /(?:^csp=|;)\s*report-(?:to|uri)\b/?
