When I float a group (with an image and description) in a text frame that is determined by a masterpage, duplicating the group changes the size of the group. This is in Publisher 2.2.1, Windows 10.0.19045.

Steps to reproduce
Create a masterpage with 2 text columns
Apply the masterpage to a document page
Fill the text frame with placeholder text
Create an image frame and a text frame below, put content in both
Group the image frame and text frame from step 4
Optionally apply text wrap to the group
Float the group in the text (pinning)
Duplicate the group (I used a hotkey for Duplicate in the video, copy paste doesn't create the bug)
Notice how the bounding box of the group has changed
Unpinned image changes size.afpub
Also, the contents of the duplicated group are left inside the masterpage folder, which I am personally not happy with, because I always have to detach the masterpage before I can edit the copied group. Same applies to copy pasting, think it is similar to what I reported here:
