Back button doesn't work when in the theme previewer

[iseulde]

To reproduce:

• Go to theme-install.php;
• Go to "popular", then to "featured" (clicking the back button here works);
• Click on "Details and Preview" for a theme;
• Click next;
• Click the browser's back button and you'll be pointed to theme-install.php.

I am not sure if I follow, anyway - does this still happen with 4.0?

Yes, it does. Sometimes the URL updates in the browser, but the screen does not, other times is just goes back to theme-install.php. E.g. when I click the back button, the URL is updated from theme-install.php?theme=x to theme-install.php?browse=popular, but the screen does not update. Another click updates it to theme-install.php, but again nothing happens.

Hello. I can duplicate this issue on 4.1. Could we tackle this with some jQuery?

$( window ).unload(function(event) {
  if ($('a.close-full-overlay').length > 0){
    $('a.close-full-overlay').click();
  }
});

I am not able to reproduce this. I am using WordPress 6.7.1, Chrome and Firefox on Windows 11.

I could not find a tab called featured, so I clicked on Popular, then on Latest, and used the back button of the browser to return to Popular. This worked well.

Then I chose "Preview" on a classic theme and used the forward arrow button in the interface a couple of times. When I used the back button of the browser, the previous theme was shown in the previewer.
I was only returned to theme-install.php?browse=popular once I had moved backwards past the first theme I had previewed.
