Collapsing behavior in header breaks when changing the "Header Scroll Settings" to "Dissappears", "Freezes" or "Fades out".

I don’t really know whether this is a fault on my side or Wix’.

Choosing “Scroll with site”.

Clicking the black box collapses the black box (Code Below). The header fills the space and the entire page follows. Everything works fine and logically, as expected.

Now, let’s try the “Disappears” option.

Collapsing the black box leaves a white void, which is definitely not logical nor intended.

When clicking into the “Header Scroll Settings” menu and selecting ANYTHING else than “Scroll with site”, collapsing absolutely breaks. Maybe I am ignorant and this is an advanced issue, but this seems so simple to fix? This seems like nothing more than an oversight, if you ask me. There is one thing that is certain: It is very annoying and unnecessary.

Most importantly, is there something I can do to fix this? Is there something I am not understanding about this issue?

export function BlackStrip_click(event) {
if (BlackStrip_click) {
$w("#BlackStrip").collapse();
} 
}
