Bug 67151 – Text selection rects render incorrectly inside spans

• Status: NEW
• Component: Layout and Rendering

[Matthew Delaney]

This affects both Chrome and Safari on Lion - didn't try anywhere else.

Steps:
1) Go to: http://developer.apple.com/library/mac/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/Introduction/Introduction.html
2) Scroll to the bottom
3) In the "See Also" section, there are 4 list items. The bottom two have spans inside. Select text in either such as "list to discuss".

Expected: The blue selection rect covers just the line.
Actual: The first line is covered plus some below, the 2nd line appears to only have a small lower sliver selected.

This is caused by the 10px bottom padding on the span containing the “quartz-dev” link on the first line.

…and in general, WebKit’s behavior here mimics NSTextView’s.

The same issue is seen in the following page.

The issue is due to "bottom padding" same as that of earlier mentioned web page.
