Multiple issues with QtQuick Studio Components Arrows

When trying to add Arrow components from QtQuick Studio Components module to 2D view, there seems to be multiple issues:

• Stop icon shown when component is dragged to 2D view, as if dropping is not allowed
• Drop still happens to 2D without releasing the mouse, multiple times even if mouse is moved away from 2D and then back to it
• Arrow components are not visible in 2D
• Arrow components are not visible in Navigator when "Show only visible components" is set

Please see attached recording. Seems to be broken since QDS3.9
