Dear list members,

Another mode related question:

When combining modes, a rather large double space appears between two mode 
blocks (i.e. where the first mode stops and the second mode begins)
In the MWE below are 3 cases. The large space is not present in the 3rd case

Is this intended behaviour?

Kind regards,
Jan Willem

======

\enablemode[X]
\enablemode[Y]

\starttext

% Case 1 - Double space present
\startmode[X]
    \input ward
\stopmode
\startmode[Y]
    \input ward
\stopmode

\blank[big]

% Case 2 - Double space present
\startmode[X]
    \input ward
        \doifmode{Y}{
                \input ward
        }
\stopmode

\blank[big]

% Case 3 - Double space NOT present
\startmode[X]
    \input ward
        \doifmode{Y}{\input ward}
\stopmode

\stoptext
