Captive portal experience is bad

Bug description:
If you connect to a wifi AP that uses a captive portal (a login screen
before granting full internet access, often seen in cafes and hotels)
with your phone, the experience is quite lacking right now.
- Webapps won't work. They try to connect to their site, are smart
enough to know something is wrong when it doesn't get the right site
back, and never finishes loading anything.
- Apps in general fail to gracefully handle the case of getting back
an unexpected result to their connections.
- You may very reasonably auto connect to a wifi AP and not receive
notifications for internet services like Telegram until you log in to
the portal or turn off wifi.
- If Browser is closed or OOM, when you open it, the last page you
were at is overridden with the captive portal page. That's lost
information! I hope you remember what it was.
- If whatever page you try to go to first on the captive portal
happens to be an https site, you will get an error instead of the
portal.
- If you know what to expect with the captive portal, you basically
have to open a new browser tab and navigate to a site you have no
intention of actually using just to get the log in page. It's a bit of
a farce and not a great UX.
- If you are *trying* to trigger the captive portal but the site you
try happens to be cached (in some way? DNS or content caching or
something), you will see that cached page instead of the portal. Which
is unexpected for you. (I *think* this happens, maybe I am
misremembering though.)
And there are probably more pain points involved. This is just off the
top of my head. Can we please guide the user through this experience
instead of leaving them with a system that acts busted?
Maybe prompt the user and open a page for them? Maybe keep using
mobile data until the portal is past? Maybe don't tell apps that they
are connected to the internet when they really aren't? Maybe have the
Browser not overwrite the last open tab with a portal?
