Bug 29648 – white-space: nowrap inline element beside a floated element wraps incorrectly without trailing textnode/newline

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Rob Retchless]

I've recently run into an issue with white-space: nowrap which is reproducible with the latest WebKit nightly.  

Broken:

<div style="width: 200px; overflow: hidden">
	<div style="float: left; width: 50px; height: 50px; background-color: red"></div>
	<span style="white-space: nowrap">Some long string that wraps</span></div><!-- </div> not on next line on purpose - triggers bug -->

Works:

<div style="width: 200px; overflow: hidden">
	<div style="float: left; width: 50px; height: 50px; background-color: red"></div>
	<span style="white-space: nowrap">Some long string that wraps</span><!-- text node (space or newline) here fixes the bug -->
</div>

Essentially, the white-space: nowrap span (or any inline element) should wrap below the float: left block if it doesn't fit, and should only spill out of its parent if it doesn't fit within the width of its parent after wrapping. Adding a space or newline after the white-space: nowrap span causes it to behave correctly.

Note: Overflow hidden on the parent is not necessary, but it makes this scenario clearer.

This appears to behave the same in Safari 4.0.3 as well.
