Right clicking in the top-left corner displays the most recently launched applet. Compared to other attachment, I moved the panel entirely and behavior remains unchanged.

Created attachment 149466 [details]
Right clicking in the very top left corner acts as if a power menu applet is present. In this case, Discord - but it will interact upon the most recently launched applet.

SUMMARY:
When using Wayland, the top left portion of the screen has an always-present (albeit invisible) button which seems to interact with the latest "Power Menu" applet. This bug takes precedence over anything in that region - including other widgets, windows, etc. Right clicking, hovering, and clicking all perform the exact same behavior as if you were interacting with a PowerMenu applet. 

STEPS TO REPRODUCE:
1. Launch KDE using Wayland
2. Click in top-left corner while an application with a power-menu applet is available (E.g. Megasync, Discord, openRGB, etc.)

OBSERVED RESULT:
Interacts with powermenu applet regardless of what other window, widget, or application elements are present in that region. 

EXPECTED RESULT:
Interaction should be imposed upon whatever elements are visually present in that region. 

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux (x86_64) with 5.18.1-arch-1-1 kernel.
KDE Plasma Version: 5.24.5
KDE Frameworks Version: 5.94.0
Qt Version: 5.15.4

ADDITIONAL INFORMATION
To better identify the cause of this bug, I have fiddled around with panels, widgets (particularly Power Menu), placement, etc. Initially, I had my panel placed along the top portion of the screen - with Application Launcher on the left, and powermenu toward the right. Reversing the placement of these items does not affect the bug. Similarly, I moved the panel to the bottom of the screen and still experienced this bug. Lastly, I removed power menu all together and still experience this bug. 

The only way that I have found to regain control of that portion of the screen is to manually close all applications that may have Power Menu applets. Once none are present, then that region behaves as one would expect.

Updating to note that this behavior continues after updating to KDE 5.25. Additionally, I've noticed that with certain display configurations the bug does not occur. On my laptop (HP Dev One), leaving the display settings to their default prevents this bug from occurring. On my desktop (which connects to a 27" 4K monitor), settings scaling to 150% with default resolution prevents this bug. Various other configurations still exhibit this problem. I've done full system restores since then, but I have not figured out what the direct cause is. For now, my best guess is that there its the result of more niche display configurations.

Can you run "killall xembedsniproxy" and confirm it goes away. Just to be certain we know what it is.

Apologies for the delay in getting back to you on this, had to wait for the bug to appear again! Anyways, killing that process did fix the issue!
