A reduction.

From http://code.google.com/p/chromium/issues/detail?id=89647

How to repro:
- Open attached html
- Focus the text area
- Type something
Typed text should appear but doesn't.

This is a kind of bandaid fix.
Although an ideal prevention for this kind of error is to deploy many invariant assertions,

The order of these lines will be fixed if you make the following changes

> LayoutTests/editing/input/style-change-during-input.html:26
> +        layoutTestController.notifyDone();

Call finishJSTest instead here.

> LayoutTests/editing/input/style-change-during-input.html:30
> +successfullyParsed = true;

You should set window.jsTestIsAsync = true instead.

Please elaborate more before you land; e.g. HTMLTextAreaElement's shadow DOM is re-created, etc...
