Highlighted measure when adding most palettes symbols by double-clicking

GIT commit: ac629b7 / Windows7

1) "My First Score"
2) Select a measure
3) Double-click on any symbols of the Repeats & Jumps palette, eg a Coda, or Segno etc. (except the first one, Measure repeat)

Expected result:

Actual result: the measure remains hightlighted, even after doing "Escape"

- The way to solve this is to drag the repeat/jump symbol.
