Faulty Visibility of Prefix/Suffix in ComboBox

[corvinsz]

Bug explanation

The TextFieldAssist.PrefixText and TextFieldAssist.SuffixText in the ComboBox are still visible even when it's content (selected item) is empty.
This doesn't line up with the other controls:

I don't believe this is an actual issue. The key difference is that you have the ComboBox set as "read only" (ie. Only selection from drop down is possible). If you make it editable like the others, you should see the same behavior as the others.

Similarly, if you make the other fields read only (if possible, e.g. using Snoop), then they will do as the ComboBox does in the screen capture.

We have this hidden "business rule" that prefix/suffix are always visible when the control is "read only".

Oh, you are right. It works as expected with ComboBox.IsEditable="True" and makes sense...
