I had to switch to 42.1 meanwhile, so have no idea wrt the current state of
Evolution in Tumbleweed.  42.1 is currently at Evolution 3.16.5 though, and
with this OS/Evolution combination at least, preformatted text does work, as
far as being able to send a patch goes.

It's useless for patch review though, see below.  Note how it inserts '>'
characters all over the place the instant you use preformatted to restore the
displayed patch to the state it was sent in, ie to undo the line wrapping that
'normal' does.
