Description

Do you want to request a feature or report a bug? Bug.

What is the current behavior? Editor does not remove selection when pasting unless mouseup has fired (it seems that a selection isn't registered until mouseup). I use a trackpad with 3 finger drag, which has a 300-ish millisecond delay after lifting. If I paste text in that window, the following behavior occurs:

draft-js

Basically, the repro steps are:

  1. Click and drag a selection
  2. Press cmd-P before mouseup

What is the expected behavior? Paste removes currently selected text (potentially not possible). Perhaps it could disallow pasting before mouseup?

Honestly, even OS X gets this wrong. Try the same steps on the location bar.

Which versions of Draft.js, and which browser / OS are affected by this issue? Did this work in previous versions of Draft.js? DraftJS: 0.10.0 Browser: Chrome 56 OS: Mac OS X 10.12.2

Contributor guide

Research direction
Examine Draft.js paste handling code to understand why the selection is not removed before mouseup. Focus on the `handlePastedText` method and the interaction with browser selection events.
