In a MacOS (Sequoia 15.6.1) environment with multiple Spaces (desktops), if the Acrobat (2025.001.20756) window with multiple tabs is opened and dragged to a new Desktop using the Mission Control Spaces desktop view, clicking on each pdf tab other than the first one will force switch the Spaces desktop back to the original desktop it was opened on.

The Acrobat window will stay put on the desktop it was dragged to, and each Acrobat tab that is clicked on for the first time will prompt this force switch. After that, they behave normally.
