Layout issues with MultiComBoxItem as ListGrid's record Component

[topr]

At ListGrids property createRecordComponent I have used DynamicForm with MultiComBoxItem field. The combo has layout: 'flow'.
User can drag records from another grid and drop no the row with combo. Then buttons 'are selected' at the combo (drop down is hidden and disabled through comboBoxProperties). This works well, but I have layout issues when a 2nd row of buttons is about to appear.
Please check the screen shots attachet:
ss1 - all is fine
ss2 - couple of buttons dragged on 4th row - layout has broken, even though no 2nd line of buttons appeared yet (look at rows backgrounds)
ss3 - two lines of button from 4th rows combo interferre with next rows buttons

How would you suggest to use layout properties any or all of the: grid, cell, form, buttons to fix that?
Keep in mind that table should remain resizable and selected buttons show fill a cell.

This would result from setting recordComponentHeight to a fixed value, whereas your MultiComboBoxItem will actually grow when buttons are added.

If that doesn't help, please show how this problem can be reproduced, with minimal, ready-to-run code.

I believe I haven't set a fixed value for this. Just left the defaults.

Please check the code attached. Just drag and drop countries from left grid to right one till rows get corrupted.
The index.html file has to be placed next to the SDK's 'isomorphic' directory.

You need to report all the information the forums prompts you for - browser, *full* version, etc. Please make sure you test with the latest patched build (see smartclient.com/builds).

I don't think it's browser dependant issue. I checked and got the same behaviour on:
Chrome: 26.0.1410.63
Firefox: 20.0
IE: 9.0.8112

Today I downloaded the latest build (SmartClient_v83p_2013-04-24_PowerEdition.zip). Still the same.

Do you need any more information from me to investigate the issue?
I'm looking forward to hear from you about how this could be solved.
