Description:
The authorization header input box placeholder is not aligned when we introduce a custom Authorization header value in the Publisher portal. Please find the attached images of both default Authorization header and Customized authorization header placeholders in the try-out page of the Devportal
- Default Authorization header (placeholder and the value are visible)

- Customized Authorization header (the input value is getting written on top of the placeholder)

Steps to reproduce:
- Log in to the Publisher and deploy an API
- Go to Runtime configurations > Application Level Security and change the Authorization Header to some custom value
- Go to Devportal > select the API > Try-out page and click on the
access.token field (the cursor blinks on top of the placeholder)
