Half the gap by removing the spacing from the hidden header

[KalobTaulien]

Closes #7110

Before:

After:

Link to sample test page: https://foundation-s-7110-halve-bn8dnw.herokuapp.com/en/campaigns/regrets-reporter/findings/

Steps to test:

• Go to https://foundation-s-7110-halve-1argxc.herokuapp.com/en/campaigns/regrets-reporter/findings/
• Turn on mobile mode for your browser (or resize until it snaps into mobile-mode)
• Open a drawer (is the first white-coloured drawer)
• Scroll down to the "Close" button. The white gap between the content and the "Close" button should be about half the height it usually is (original page for reference: https://foundation.mozilla.org/en/campaigns/regrets-reporter/findings/)

Hi Kalob! Thanks for tagging me in this and leaving easy to follow testing instructions.

I have taken a look at the page on mobile, and can confirm that the height is smaller than what it originally was.

I also took a look at the code, and everything looks good to me! Approving 👍

Hey, sorry I didn't look at this sooner. I still see "no such app" at https://foundation-s-7110-halve-bn8dnw.herokuapp.com/en/campaigns/regrets-reporter/findings/

We need a working Review App for this. Moving to blocked until the review apps come back online for us.

@danielfmiranda do you need me to do anything on this? I still can't review it.

Looks good! Thank you Daniel!
