SUMMARY
Copy/paste via wl-copy does not automatically add to clipboard. Instead, a wayland icon appears on the application panel and needs to be clicked to activate it.

STEPS TO REPRODUCE
1. Open terminal
2. wl-copy "test"
3. Click the wayland icon that appears on your application panel

OBSERVED RESULT
wl-copy does not get automatic focus

EXPECTED RESULT
The text/input is copied to the clipboard immediately.

ADDITIONAL INFORMATION
I was able to fix this by going into my Window Management settings and setting Focus Stealing Prevention from "Medium" to "Low". However, I believe this should not be necessary; something like a clipboard util should surely be an exception and before a recent update this did not happen.
