Description

MacDown v0.4.4.1 (624)
OS X 10.10.3

The preview update is not rendered asynchronously. This is unfortunate for fast typing. I think this bug is new and doesn't exist in older versions.

Research direction

Start by reproducing the preview update behavior described for MacDown v0.4.4.1 on OS X 10.10.3 while typing quickly, then trace the preview update path and how it interacts with the editor pane. Done means preview rendering no longer blocks fast typing and the behavior is verified against the reported case.
