This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Currently, only mozilla offers the mozInnerScreenX and mozInnerScreenY attributes on iframes -- this detects the location of the iframe in relation to the topmost frame. This is very useful in a number of contexts, including detecting when the iframe is on screen. Could we add equivalent attributes to HTML5 standard? window.innerScreenX / Y? Link to discussion of this issue on webkit forums: https://code.google.com/p/chromium/issues/detail?id=151983
Here is a link to the mozilla api for this functionality https://developer.mozilla.org/en-US/docs/Web/API/window.mozInnerScreenX
HTML5.1 Bugzilla Bug Triage: This bug constitutes a request for a new feature of HTML. Our current guidelines, rather than track such requests as bugs or issues, is to create a proposal for the desired behavior, or at least a sketch of what is wanted (much of which is probably contained in this bug), and start the discussion/proposal in the WICG (https://www.w3.org/community/wicg/). As your idea gains interest and momentum, it may be brought back into HTML through the Intent to Migrate process (https://wicg.github.io/admin/intent-to-migrate.html).

Would you like me to start the discussion in the WICG or have you already taken this step?
@mbenisch If you could please start the conversation over on WICG yourself that would be great.
