avoid empty blocks when hiding ads

What does this MR do?

2024.10 or 2024.11 added a <div> around <MkAd>, but while MkAd checks if ads should be shown, and generates an empty <div> if not, the wrapper div was always shown.

This commit takes the same logic from MkAd and applies it to the wrapper as well.

thanks to @puppygirlhornypost for noticing
