Rev. dbdd742 introduced the 'baseMode' parameter of field's nodes
in the BasicRenderer. Its purpose is to encode the generic mode
of the field, regardless of its readonly modifier (i.e. in form
views, the baseMode of all fields is the mode of the renderer and
in list views, the baseMode of all fields is 'readonly', except for
fields in the row being edited, whose baseMode is 'edit').
Unfortunately, when the value of the readonly modifier of a field
was 'readonly', its baseMode was changed from 'edit' to 'readonly',
which shouldn't, as the baseMode's value should not be affected by
the modifiers.
This produced a bug when a field had a readonly modifier, as once
its value became true, the field was rendered in 'readonly', and
whatever the value of the modifier afterwards, it always remained
in 'readonly'.
The rev. ensures that the baseMode is no longer impacted by the
value of the readonly modifier.
Closes#22729
