Description:
Select boxes in "tunneled dialogs" don't have a button that indicates that a list of selection can be opened. Those widgets usually have a button with a small arrow which indicates that the list will expand when clicking on it 

In the iOS app the said buttin is somehow shown, but is not complete and misses an icon (or similiar).

Steps to Reproduce:
1. Create a writer document in the iOS app
2. Create some text, select it and click "Edit > Edit paragraphe style" in the menu (Bearbeiten > Absatzvoralge bearbeiten... in German)
3. Chose for example "Font Effect" and check the select box right next to "Overlining"

Actual Results:
The select box misses some pixel of the right border and there is no "arrow" indicating that one can expand the list.

Expected Results:
The select box should have a border on the right side and an "arrow" icon should indicate that one can expand the list/view.


Reproducible: Always


User Profile Reset: No



Additional Info:
It seems that this does not happen in all cases, some select boxes are complete. See attached printscreen.
