Troubleshooting - Header Code Injection Carries Over Between Page Loads?

Hello, 

I'm working on doing some refreshes to an existing 7.0 site, so I made a copy to test some things out on. You can find it at: https://clownfish-manatee-ngnn.squarespace.com/ password: mhf

On the Dahlia Tubers / Dahlia Shop page I added the following code in header code injection to 1) insert a custom header that was different from the rest of the site 2) hide some header elements and 3) add a border and shadow to the body of the page. (Forgive the inline styles, while I assigned a class I did not add any CSS here as this was a quick mockup). 

<div class="custom-header" style="width: 100%; text-align: center; 
  background-color: #4a574b; color: white; 
  vertical-align: center; line-height: .5em;">
  <p>Morey Hill Farm</p>
  <h1 style="color: white;">DAHLIA SHOP</h1>
  <p style="padding-bottom: 20px;"><a href="/home">Return to Main Site</a> | <a href="/cart">Cart</a></p></div>

<style>.Header-inner, .mobile-bar  {
display: none !important;
}

  .Main {padding-top: 0px; border-radius: 10px;
  -webkit-box-shadow: 3px 4px 2px 0px rgba(0,0,0,0.45);
-moz-box-shadow: 3px 4px 2px 0px rgba(0,0,0,0.45);
box-shadow: 3px 3px 2px 0px rgba(0,0,0,0.45);}
  .Main-content {padding-top: 50px;}
</style>

It's displaying on desktop as expected (haven't worked on the mobile header elements fully). The problem I'm having is when visiting the dahlia page then navigating to other pages, specifically the homepage which is actually an index page, the code seems to still be loading and breaking the banner image. The image should be displaying as a full-screen bleed as seen at moreyhillfarm.com

Any ideas? 

P.S. Ajax loading is currently disabled but it seems to be an issue if it's on or not. 

I'm not seeing the issue.

Does the same thing happen when in private browsing?

The behaviour you describes sounds like Ajax loading is active.

I recorded a quick clip to show what I'm seeing. This test was in the latest version of Safari, but also occurs in Chrome. I double-checked and Ajax is off.

I'm unable to view the video, the forum is reporting an error.

Here's the video showing the issue I'm having. 

Ah. Now I think I have a handle on the issue.

For the Return to Main Site link, set it to / (forward slash). It is currently going to /home, which is it's actual slug but the homepage < https://clownfish-manatee-ngnn.squarespace.com/ > is a special case and is the second URL for your home page. An alias if you will that SS sets up when you make a page the home page.

If that fixes the issue then you can turn on Ajax again if you want.
