Twenty Twenty: Cover template not displayed correctly in Safari and Chrome on iOS

[yari2u]

When using the Cover template in Twenty Twenty, the height of the cover template is displayed wrong in Safari and Chrome apps on i0S (on all versions since the creation of the theme). This means that people don't see the title of the page or the downward arrow on the cover template on their iPhone / iPad (or only see a part of it if the title is long enough). Both Edge and Firefox apps on iOS show the cover page correctly.

@anlino Would you mind helping with this one as it really should get fixed to make the cover template useable in mobile devices? (Great theme by the way, I really enjoy using it ;-)
