Artboard Custom Resize Bug
When manually updating artboard dimensions, the artboard itself no longer previews your changes, you have to click "Update while dragging" to see the size before closing the window.
Artboard dimensions sometimes automatically revert back to previous values, if the new values are close in number. For example changing 423mm to 420mm, the value in the box would revert back to 423mm immediately.
No specific files, this happens in general.
