'Authentication Secret' field is not a textarea

[jonalmeida]

On the Web Push: Data Encryption Test Page , the 'Authentication Secret' has a box to enter the secret into it but it doesn't seem to be a textarea like the others.

I had to edit the HTML to allow me to add a secret.

Related: the 'Encrypt the data' button was also disabled, but that might be a side-effect of changing the page contents manually.
