For very small hotspot regions when trying to select handles on adjacent
strips, selection can sometimes jump to the strip farthest away from the
current mouse cursor position. This happens regardless of "Tweak
Handles" setting, but is most noticeable when it is off.
In the case that two strips are selected at once (which is possible
because internally strip handles are shifted away from the strip body by
a third of the handle size), `mouseover_strips_sorted_get` attempts to
sort these strips to maintain priority, but the logic was backwards --
fix the glitch by sorting strips such that the first strip in the
`Vector` is always the strip closest to the mouse cursor.
