Hi,

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

I am trying to conditionally render my Chip component to be clickable or read-only. When I set clickable={false}, it still executes onClick when pressed.

Expected Behavior 🤔

I would naturally expect that both UI and the method execution would be disabled by the clickable={false} option.

Steps to Reproduce 🕹

I added a quick sandbox example here to reproduce: https://codesandbox.io/s/vigilant-water-2yygy?file=/src/App.js

Steps:

1. add onClick method
2. add clickable={false} line
3. click on the tag in the UI
4. it still executes the onClick() method
