Expected and not expected after downloading PDF

After update to iOS 15.4.x, my PWA users "added to home screen" suddenly got white status bar after downloading PDF, see attachments. Please help?

Clip from index.html
<link rel="manifest" href="manifest.webmanifest">
<meta name="theme-color" content="#69d01b">
<meta name="theme-color" content="#69d01b" media="(prefers-color-scheme: light)">
<meta name="theme-color" content="#69d01b" media="(prefers-color-scheme: dark)">
<meta name="mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent">

<style>
  body {
    background - color: #69d01b!important;
  }
</style>

Clip from manifest.webmanifest:
"theme_color": "#69d01b",
"background_color": "#69d01b",
"display": "standalone",

Clip from download script:
import { saveAs } from 'file-saver';

saveAs(
    new Blob([bytes], { type: 'application/pdf' }),
    `${filename} _Preview.pdf`
);

Thanks for filing, I think this issue may require a fix outside of WebKit. Can you please file a report via feedbackassistant.apple.com and include a sysdiagnose and a link to the PWA? Thanks.

How to create an sysdiagnose? The PWA is not public, login is required.

I get no response at feedbackassistant.apple.com.

I have now created an demo to show the error: https://mango-tree-0ed834c03.1.azurestaticapps.net/

Any status on this, is it still happening in iOS 15.6? Cannot access the radar link.
