Bug 126053 – Add a test for reattaching collapsed whitespace when siblings change style

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Ryosuke Niwa]

Merge the test from https://chromium.googlesource.com/chromium/blink/+/dd5636728643ff958aebeaf064d38754b0d5904b
so that we may not introduce the same regression in WebKit.

Is there a way to write this 400 as “more than half the width of ” something?

Replaced it with container.offsetWidth * 2 / 3.
