I don't think this is a Tauri-specific issue, but I decided to try it just through a local Apache web server using Safari 14.1.1 on macOS 10.15.7 out of interest.

I made only three changes to your https://github.com/olegshilov/tauri-testing/tree/iframe-issue/app:

• In index.html, I changed the start of each path from /iframe.html to ./iframe.html (because I was in a subdirectory of the web server).
• I added the HTML to iframe.html to print out the URLs:

  <p>location.href: <span id="loc"></span></p>
  <script>document.getElementById("loc").textContent = location.href</script>

• In index.html, I also increased the iframe width to 500 to see the full URL:

Curiously it works fully over Apache. Can't immediately explain why it's behaving different in the Tauri context.

Also works over the file system (rather than a web server) with Safari:

@shirakaba hi. it's Tauri-specific issue because we detect the place where it happened
