Problem with Split Menu > Mega Menu > Search input

Hello!

I have a problem I was hoping you could help me with.

I'm using the split menu with a single mega-menu dropdown.

Whenever you are scrolling and click the search trigger, the search placeholder text overlays the mega-menu title.
I've been trying for days to figure out how to hide the mega-menu link title when searching (and sticky scrolling) but cannot find a solution.

Can you help? I'm sure it's just adding one line of CSS but I can't find it.

Here's my example:
