Summary0033295: Combo in csOwnerDrawEditable
DescriptionComboBox in csOwnerDrawEditableFixed and csOwnerDrawEditableVariable does not display any text at design-time. Text is displayed correctly at run-time.

I guess there is no need to override DrawItem method for edit line in these styles.
Steps To ReproduceOpen demo project. Set any Text property or ItemIndex to 0, 1 or 2. Edit line of ComboBox is empty.
Run project - text will appear.

This seems to be Qt issue (and all Styles).

I tried with Lazarus 1.8.0 r56594 FPC 3.0.4 i386-win32-win32/win64 and it displays text at design-time for all styles except csDropDownList.
