Reversing a clip plays the wrong part if it's trimmed

Bug Description

If I have a 10 second clip that I've trimmed down to 4 seconds (say 2 seconds from the front, and 4 seconds from the back), then duplicate it and reverse it, the reversed clip plays the wrong section.
Essentially, it reverses the clip, but not the "window" into the clip.

To "fix" this, we need to reverse the trim. So our trimmed reversed clip needs 4 seconds trimmed from the front and 2 seconds from the back.

This makes sense once you understand it, but most people wouldn't realise that after trimming a clip to exactly what they want, why reversing it doesn't work. The reverse effect would often be used in the middle of a clip, i.e. you have a clip of a dog running, you cut out a short funny section, duplicate it so you have 3 copys of it, and reverse the middle one, so that the dog now appears to run along, do the funny thing, do the funny thing in reverse, do the funny thing again and continue with the rest of the main clip, all seamlessly.
