Issue running 2 instances of the Web Player at the same time

here's the backstory

I run a 2 monitor desktop system, and watch most of my Plex on it. In the Past I could have the web client open on 1 screen in a window, and could browse my library, look at live tv schedules etc on the other monitor in a separate web client. Several updates ago one of the updates broke this (I'm thinking Less than 4 updates). Now if I try and launch two separate clients, it seems like only the last one to play video in (Maybe cookie persistance?). Another thing that may be related is that the losing 'session' constantly prompts me to sign back in.

I've tried it in both

Chrome/Chrome Chrome/Edge

Test environment

PMS Version: Version 1.22.3.4392 PMP Version: Platform (Windows 10 Pro v1909 Build 18363.1500 )

Steps to reproduce

1. Open two instances of the Web Client
2. Try and play video in both

Current behavior

1. only 1 seems to work

Expected behavior

1. Both used to work

It's always going to be uncharted territory to run the app multiple times in the same browser. Each instance assumes it's the only one when in reality all tabs running our app are using the same storage. Running two separate browsers should be 100% fine; the Chrome/Edge case shouldn't fail.

Simple workaround: open the local web app in one browser window and the hosted web app in the other.

Side note: this repository is for Plex Media Player, which is not the same as the Plex web app.
