Listbox mouse issue with showmodal

Does anyone experience this? Happens on any computer I test it on.

OS: Ubuntu (latest)
Xojo: Latest
Repro steps:

  1. Listbox control with multiple pages of items
  2. Select all items in listbox
  3. Open another window on top using ShowModal()
  4. When window closes and you move the mouse across the listbox it scrolls automatically changing the selected items
