Don't emit duplicate decorations. #3635

Closed s-perron closed 3 days ago

s-perron commented 1 week ago

It is invalid if the same decoration is applied to the same id multiple times. This adds a check before adding a decoration that the decoration is not alreay in the list. If it is, then the duplicate is not added.

Fixes #3627
