Bug ID: 47788
           Summary: Combobox should not close while using keyboard letters
           Product: Wine
           Version: 4.16
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Example:
- Run "wine control intl.cpl"
- On the first tab, click the top combox to open it
- Type down a few letter, like 'G', 'E', 'R'

It should jump to the first entry starting with "GER" while keeping the
combobox open. Instead it closes the combobox.

Might relate to bug 42898.
