Dock Remains Visible in Fullscreen Applications

I actually have no idea how this slipped past Apple and more importantly where to report this. If the community has any suggestions to fix, this would be great!

Hardware: 2016 15" MacBook Pro, 16gb RAM, 2.7ghz Intel Core i7 Processor, 512gb of Storage, Intel HD 530/Radeon Pro 455 GPU

Software: macOS High Sierra 10.13.2 (17C88) (also experienced on earlier versions)

I'm running the latest High Sierra (10.13.2) on my MacBook Pro. This bug has actually been happening since the original versions of High Sierra but I was hoping maybe it would get sniped by someone at Apple, I guess none of them use external displays. When I'm home, I dock my MacBook into an external 1080p display and then I take it out when I'm on the go. Either of these scenarios will cause the dock to act odd and stay visible in fullscreen applications. To clarify, this is any fullscreen application: Finder, Activity Monitor, Safari, fullscreen YouTube videos, etc. The dock remains visible no matter what I do. I'm unable to use Cmd+Shift+D to hide the dock in fullscreen and I have to exit fullscreen, hide the dock, and then go into fullscreen again. This persists until I reboot or log-out and log back in. Logging out and logging back in is fine but the minute I dock my MacBook again, it starts again! So I have to log out and log back in, AGAIN. It's incredibly annoying when I'm trying to watch fullscreen YouTube content. I actually don't have any other High Sierra capable machines so I can't test and see if this is just a bug with my particular install/MacBook.

The best part: the dock fades like it wants to hide and just comes back again!

Here's a video showcasing it: dock sticking in fullscreen on High Sierra - YouTube

And of course, some appropriate screenshots

Another "temporary" (until i dock the MacBook again) fix is to use Terminal to kill the dock but of course, that puts all my windows back on the screen again.

Has anyone else experienced this or am I going crazy? and if you have, what can i do to fix it? (besides not use my Pro laptop as a Pro laptop and use it with an external display 🙄
