2. In old sandbox example You can see it near "Text 3 Text 3 Text 3 Text 3",
when setting and clearing group 2 buttons, when [ + ] and [ - ] is not in
same position, that screen shot is from real page.

I see. When a  is disabled, even if it has a position: absolute, Firefox still considers that the column is there. I recommend you reorganize your code to move the <xforms:group> inside the :

<xhtml:td>
    <xf:group ref=".[instance('groups-bug')/b = 'true']">[ - ]</xf:group>
    <xf:group ref=".[instance('groups-bug')/b != 'true']">[ + ]</xf:group>
</xhtml:td>

Also see the updated file: group-space-leak.xhtml.

3. Yes it makes sense, because, if user slowly input 10 letters long word,
then there are made 30 database requests.

Good point. I added a bug for this:
