Bounding box of Add-on Curve Spirals is too big

First time reporting bug, so please bear with me :-)

  • Open new general file
  • Edit Preferences -> Enable Add-on Curve Extra Objects
  • Delete cube
  • Add -> Curve -> Curve Spirals -> Archemedian
  • Set: Turns 3, Height 1, Radius 1, 3D, Poly (any settings seems to cause problems)
  • Exit edit mode
  • Turn on bounding box: Object Properties -> Viewport Display -> Bounds (tick)

Bounding box should hug the spiral outline but it is much bigger than geometry. I noticed this in Geo Nodes when I was trying to work with bounding box node and a spiral. Works fine in 3.4.1 but has been broken in 3.5 for a few weeks.
