[no-dupe-class-members] Cannot turn off rule

Repro

https://gist.github.com/twhitbeck/0235fc09ee7076a4f60a5c42107e73d2

Expected Result
Running yarn lint should succeed

Actual Result
Running yarn lint fails with errors because of rule no-dupe-class-members even though that rule is turned off.

Additional info
I did verify that this is not an issue with a vanilla js project with same version of eslint and using { "extends": ["eslint:recommended"], "rules": { "no-dupe-class-members": "off" } }.

Versions

package	version
@typescript-eslint/eslint-plugin	1.9.0
@typescript-eslint/parser	1.9.0
TypeScript	3.5.1
ESLint	5.16.0
node	12.3.1
npm	6.9.0
