Alt-tab-macos: YouTube fullscreen windows in Firefox Developer Edition don't show in AltTab

[overseeing]

Describe the bug

As in title.

Screenshots / video

Not needed, easy to reproduce. (I reproduced in a new macOS user.)

Steps to reproduce the bug

1. Install Firefox Developer and simply go a a YouTube video and make it full-screen.
2. Now toggle AltTab. Notice that (current) window is missing. Means you can't alt-tab back to it again either. If I alt-tab away my only way to get back to the window is to find it in Mission Control.

I think it's a buggy behaviour in Firefox Developer, and normal Firefox doesn't do the same thing, but whatever it is maybe other apps could produce the same scenario so it's worth finding a way to work with such anomaly. I work with a multitude of browsers concurrently.

Hey @mindfulsource, thanks for sharing this issue!

I'm pretty sure I know what the issue is already. I made a fix for Firefox previously in #360. That fix whitelists Firefox bundleIdentifier and allows its fullscreen windows to show up. Firefox Developer has a different bundleIdentifier: org.mozilla.firefoxdeveloperedition.

I can whitelist this app too. These workarounds are a pain. I opened #456 to discuss a better way to handle things, but it needs a breakthrough idea. Nobody has found a better approach that the current one so far, unfortunately.

It's a messy problem. Too permissive, and garbage windows start showing up (#386); too restrictive, and actual windows don't show up, like here.

I made a fix. It will ship in the next release. If you want to help with the big picture, please look into #456

I've found another app not showing up in AltTab: Adobe Audition 2020. Should there be a single Issue for people to report apps in or you're OK if I update this one with other finds?
