make subnode rows the same height for rows without dropdowns

[George Gelashvili]

Hello Hackers,

We found that in subnodes without dropdowns, the rows had smaller height,
making them appear unintentionally different than those with dropdowns. An
example place in the app is Create Table ->
Security tab -> add a row for each of Privileges and Security labels.

Attached is a fix.

Thanks,
Shirley and Shruti and George
