Bug 18203 – Right floats should be allowed to overflow past left border edge

• Component: CSS
• Status: RESOLVED FIXED

[Dave Hyatt]

See:

http://css-class.com/test/css/overflow/float-container-margin-overflow.htm

In current WebKit, the right float is not allowed to have its left edge extend beyond the left border edge.  This is not correct according to the CSS2.1 spec and does not match Firefox.

Remove the clamping code

Remove the code that clamps right floats to the left border edge.

I will land this patch with a better test case that doesn't depend on resizing the window.

r=me because I know you'll add a ChangeLog and test case -- but why not do that before setting the review flag next time?

Because keeping a ChangeLog in my tree for days is a giant pain when I'm doing other work.

I have created a new test case without the need for scrolling. Just one element floated right. Firefox will hide the left edge of the float beyond the left edge of the viewpoint. Safari will show the full width of the float causing a horizontal scrollbar. See:

Hyatt, are you planning on landing this?
