See the following test case. Run it and fill the fill-in so that the cursor wraps to the next line. Observe the unexpected cursor position on the next line.

The issue was identified in #7863-7.

def var fi1 as char format 'x(256)' view-as fill-in size 160 by 1.
def frame f fi1 with side-labels size 200 by 20.
enable all with frame f.
wait-for close of this-procedure.

Enter data or press F4 to end.

It seems that fill-in is forced to be wrapped ignoring the fact that containing form is scrollable.

Is wrapping even a valid ChUI use case?

I can't tell. But OE allows it.

There are two issues:
first - there is no label on initial screen, the issue is caused by a ScrollEvent sent when FILL-IN is getting focus.
second - for some reason clipping is removed so instead of being clipped accordingly full contents of the fill-in is drawn on the screen.

Those initial focusing events seem to be GUI specific, I've disabled them for ChUI

second - for some reason clipping is removed so instead of being clipped accordingly full contents of the fill-in is drawn on the screen.

In case FillIn is refreshed with FillIn.refresh() no clipping information is present (like it is when a full redraw) thus no clipping occurs. Trying to find whats going on there.
