Antetype seems to have picked up a bug where bounding boxes don’t always update.
thank you for reporting, I found two other issues for the not-updating bounding box (if canvas is zoomed above 250% and moving the cell with the cursor keys (in free layout) after dragging the cell with the mouse). Added your issue, we will have a look what went wrong here.
Also happens when you have a scrollable list. You select a cell, scroll and the bounding box remains in the original position instead of scrolling with the selected cell. Same issue as the other cases I assume, but I wanted to mention it nonetheless.
