Description

TreeDropdownField, CheckboxField and some other fields have a misleading appearance in read only mode. This problem occurs mainly when using these fields in modal windows, when the form has the read-only status and the fields do not yet have any value. In this case, these fields has misleading appearance. See images.

We should apply the same styles for these fields as for the normal state of these fields having or not having any value.
