Hi,

"unfortunately" i did not manage to reproduce the odd behaviour with
the editors being removed im my sscce, but the combobox problem
(described in paragraph "Without terminateEditOnFocusLost") arises here
(with and without that property set). I will further investigate and
try to reproduce the problem with editors being removed; In the
meantime the following serves as sample for the ComboBox problem (which
might be in some way related to the editors-being-removed-problem).

How to reproduce the problem with the sample code:

1. click on cell with "ab" in it
-> combobox appears and pops open
2. select some value
-> combobox closes its dropdown and displays new value
3. click on cell with "bb" in it
-> new combobox appears, but is closed
 (i do not see the box pop open and close again; i think it is due to
the example
  running faster due to the rather simple list content)

Whenever the combobox editor is active, clicking on another cell with
the combobox editor gives the described behaviour. When another or no
editor is active, the combobox pops open as it is supposed to.

any help is greatly appreciated.
