What to do if you already signed the CLA

Individual signers

• It's possible we don't have your GitHub username or you're using a different email address on your commit. Check your existing CLA data and verify that your email is set on your git commits.

Corporate signers

• Your company has a Point of Contact who decides which employees are authorized to participate. Ask your POC to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the Google project maintainer to go/cla#troubleshoot (Public version).
• The email used to register you as an authorized contributor must be the email used for the Git commit. Check your existing CLA data and verify that your email is set on your git commits.
• The email used to register you as an authorized contributor must also be attached to your GitHub account.

CLAs look good, thanks!

Thanks for the PR. In this case, the instructions are correct. If you follow the instructions, you should see the pressed icon toggle is blue. because that rule is overriding the one in :host.

The docs describe this:

"The demo-element selector matches the element and has a higher specificity than the :host selector inside demo-element. You can use this fact to specify your own values for custom properties that the author of a custom element has defined inside that custom element, without altering the element's code."

Hope that helps. Please feel free to follow up if it's still not working for you.
