            Bug ID: 24787
           Summary: Remaining issues for sticky positioning on CSS
                    Positioned Layout Module Level 3 Draft
           Product: CSS
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Positioned Layout
          Assignee: dave.null@w3.org

URL: http://dev.w3.org/csswg/css-position/#sticky-positioning

Issue 1: 
Describe which element font-size-relative units are resolved against. 

Issue 2: 
Say what happens if this rectangle is empty.

Issue 3: 
Say what happens if it already overflows the containing block

Issue 4: 
Do marins collapse between the stickily positioned element and its containing
block element? 

Issue 5:
Does the margin on the stickily positioned element affect its distance from the
flow root edge? 

Issue 6: 
Sticky positioning should really be defined in terms of the nearest scrollable
ancestor, but there is currently no such term defined elsewhere in CSS. CSSOM
View refers to "scrolling boxes." CSS Overflow has yet to pull in the relevant
text from CSS Box, and CSS Box has an old, confusing definition of "flow root"
which is almost (but probably not quite) what we want here. This spec refers to
"flow root," since that's the closest thing currently specced somewhere, but
this is not optimal.
