Installing Mastodon from the browser as a PWA causes multi-column to not work and the URL can't be changed

[CliffWade]

Steps to reproduce the problem

1. Pull up Mastodon in a browser with Advanced Web View enabled, and with the setting enabled via your profile to always view Advanced Web View.
2. Install Mastodon as a PWA via the browser(Vivaldi in my case, but have tested with other browsers), close the PWA when it opens.
3. Restart the PWA again, and you will notice that the app isn't displaying Advanced Web View, even though the browser is and has the correct new URL with the new /deck/ in the URL address.
4. Since my specific instance is hosted on MastoHost, I can't change the URL in the manifest in any way to force the PWA to open with the new Advanced Web View URL. This means that you are forced to click the link at the top of the single column view every time you open the PWA.

Expected behaviour

The PWA should include the new /deck/ part of the URL so that when the PWA is launched, it will open in Advanced Web View, just as your settings tell it to do.

Actual behaviour

When hosted at some place like MastoHost in my case, we don't have the ability to edit the URL of the installed PWA to force the PWA to open in the Advanced Web View as it does in the browser when using the correct new URL with the /deck/ part included in the web address.

allthingstech.social but this will happen with any instance that's hosted on MastoHost and similar. If it's a fully hosted instance, then they have the ability to change the URL via a manifest file.

This is actually a regression in the latest version. It used to work fine in both mobile and desktop modes. Since the new update, it doesn't default to that.

You have to click preferences then "back to mastodon" and you get the advanced interface again. You don't have to anything else, like toggling the setting, just go into it and out again.

Thank you for opening the issue, it's happening for me as well. With Android 13 and Chrome.
