Slurs not visible till completion in during note entry mode (0.9.6 regression)

"Not sure if it's a bad or good thing, but the behavior during note input has changed.
In 0.9.5,
Enter a C, press S, the slur appears, enter C, enter C, press S and you have a 3 notes slur

In r2177,
Press C, press S, nothing visible happens, press C, press C, press S, and the slur appears."

I prefer the visual feed back you got in 0.9.5 during editing. In the latest revisions I second guess myself on whether I actually pressed S.
