Logic creates ghost/hidden plugin instances when rearranging the plugin order

Hi,
this post is not about a Juce issue, however I thought it would be a good idea to post it here.
The issue is described in this post on logicprohelp.com Massive bug in Logic 11 and 11.0.1 - ghost plugins created & process audio when rearranging plugins - Bugs & Workarounds - Logic Pro Help

and it seems it has been around for ages, at least from version 10.6.3

Has anyone seen/experienced this issue before?
It’s an important issue and I’m just wondering how did Logic developers missed that.

Thank you!
