Overview

Totp setup dialog should strip newlines.

Steps to Reproduce

Some websites provide the TOTP secret with this HTML markup:

<div>
  <p>ABCD EFGH IJKL MNOP</p>
</div>

If you triple-click the TOTP, copy it, and then paste into the TOTP setup dialog, then it will give the error "You have entered an invalid secret key. The key must be in Base32 format."

If you paste it into a text document you will see that there are two newlines before the code, and one newline after it:

ABCD EFGH IJKL MNOP

Expected Behavior

This code should also remove newlines.

Actual Behavior

"You have entered an invalid secret key. The key must be in Base32 format."

Context

I have encountered this problem on several websites. For example, Twitter has this problem.
