I don't even know what TRT is.

Resizing of the windows with the mouse is closely related
to the modeline ... in particular, if you have scroll-bars
the tiny line between modelines is indeed the only way to
resize two side-by-side windows.

.. if there is no modeline, there is no place to grab.

So it is definitely not trivial to fix this.

Since this is not a new bug, I suggest that we make an entry in TODO
for looking at this _after_ the release.
