Password leak to clipboard manager in KDE Plasma

[aardbol]

Application version: [e.g. v1.1 - it is shown in About window] 1.4.2
Operating system: [name, version, 32/64 bits, kernel version (if Linux) ] manjaro linux KDE Plasma kernel 5.9
Device model and firmware version: [Pro v0.8/Storage v0.45 etc.] Pro 2 v0.11
Connected USB port type: [1.1/2.0/3.0] 2.0
Issue occurrency: [always/sometimes/once] always

Expected behaviour

Passwords should not appear in the clipboard manager

KeepassXC for example handles passwords properly: keepassxreboot/keepassxc#1969

Current behaviour

They are stored there (and stored on the drive by default)
