Bugs with Header on "Responsive" Sites
A site is set as responsive (toggled to "on").
The site also employs the shrinking header.
We wanted to hide the header on a single page (building a landing page).
Whenever we hide the header, it later reappears on its own. I can reproduce the issue by copy-paste any element on the page. Upon "paste" the header reemerges.
I was advised (incorrectly) by support that this is "deliberate" (LOL) and that the workflow to hide the header is this:
1) go to Design ➜ Layout and toggle the Responsive setting to off
2) hide the header on the desired page
3) turn Responsive back on.
"Then the header won't reappear."
However, when the header is hidden on the non-responsive site, once responsive is turned on, the page renders with a big empty space where the header was previously.
So, it is clear that: RESPONSIVE, SHRINKING HEADER, and HIDE HEADER ON PAGE do NOT work together.
I also recall there being issues with Responsive and Overlapping Headers. But, I can't document that here at this time.
