[Bug] Icon too large

[jclsn]

Describe the bug
The icon is significantly larger than other panel icons and does not blend in well

[korapp]

Reason
Small icons are rendered inside the System Tray plasmoid (only when Panel Icon Size is set to small). Standalone icons are larger by default, as you can see below.

I know that the HA icon is still a bit bigger but that's another matter.

Solutions
You can change the Panel Icon Size to Scale with Panel height adjust the panel height to get the icon size you like.
Or
I could enable the plasmoid to be the tray item, if you don't mind it getting a default header:

I would actually prefer the latter solution. I think it looks better in the system tray, but up to you in the end :)
