CEU15-Trim to Intersection broken or at least not working as v8i

Have just found that Trim to Intersection is either broken in U15 or at least doesn't work as v81. See screenshot below and sample attached.

I started Trim to Intersection using PM 7,4, picked the angled part of Line 1 and then Line 2. What I want to see is the result as shown in V8i-Complete, but didn't in U15.

I'm assuming that this is a bug in U15.
