Copy button on 'Generate Password' does not work on KDE Plasma

[ronnocnave]

When I generate a new password using the password generator tool on KDE Plasma, pressing the 'copy' button does not copy the newly-generated password. Highlighting, then right-clicking in the newly-generated password field and selecting 'copy' does work, however.

Expected Behavior:
Pressing the copy button actually copies the new password to Klipper in the #1 spot for use in the OS.

Current Behavior:
Copying the password via the copy button does not appear to do anything.

Steps to Reproduce:

1. Open password generator tool
2. Generate new password
3. Click the 'Copy' button

I cannot replicate this in Ubuntu 19.04 using KDE Plasma 5.15.4
