Comments should close when any interaction is taken on the canvas. This is true for PCB but not for Schematic. Today, comments only close when these actions are taken: On Schematic: the canvas is clicked or another comment pin is clicked, ESC is tapped. On PCB: the canvas is clicked, any object is clicked, a wiring touch point is clicked, another comment pin is clicked, area select is used, ESC is tapped. We're missing on schematic: an object is selected. area select is used (even when nothing gets selected as a result). wiring initiates.
