Rules options CSS selector ignored

Expectation: Only run rule against elements matching value of selector key. In sample config code below ‘scrollable-region-focusable’ is where the issue occurs.

Actual: selector key of rule options is ignored.

Motivation: Broken functionality. Looking to limit which elements are tested on a per rule basis.

        'html-has-lang': { enabled: false },
        'scrollable-region-focusable': {
          'selector': ":not([class*='dropdown_length-'])"
        }
      }

It looks like you are trying to pass this config in through axe.run, is that correct? The axe.run config only supports enabling/disabling rules. If you wish to configure more about a particular rule, you will need to go through axe.configure and override the rules selector there:

axe.configure({
  rules: [
      {
         id: 'scrollable-region-focusable',
         selector: '*:not([class*="dropdown_length-"])'
      }
  ]
});

If doing this for automated testing, you can configure the rule before the test and then reset the config afterwards using axe.reset().

I think we have a sufficient solution. Going to close the issue.
