Version: 51.0.2681.0
OS: Reproduced on Windows 10 and Mac OS X 10.11.3

What steps will reproduce the problem?
(1) Open https://www.rememberthemilk.com/app and sign in
(2) Click on any contenteditable field such as "Add a task", "Add a note" or "edit" a note
(3) Try adding spaces at the end of the input or in the middle.

What is the expected output? What do you see instead?
The spaces should be added as expected but here something swallows the trailing space and collapse several spaces into one.


The application works correctly on stable on Windows 10 so this is a clear regression on Canary. Adding ReleaseBlocker-Stable to this as it's a pretty popular website and the bug renders it close to unusable.
