Bug 112806 – [BlackBerry] compositing/iframes/scroll-fixed-transformed-element.html fails in manual testing

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit BlackBerry

[Arvid Nilsson]

PR 283363

When visiting jquerymobile.com, or manually scrolling around LayoutTests/compositing/iframes/scroll-fixed-transformed-element.html, you can see that in the BlackBerry port, fixed positioned elements inside an iframe are positioned correctly only when you scroll that iframe, not when you scroll the main frame.

When scrolling the iframe, the fixed pos element is positioned as if it was fixed with respect to the iframe's viewport. When scrolling the main frame, the fixed pos element is positioned as if it was fixed with respect to the main frame's viewport.

The effects of the bug are only visual, i.e. not detectable by DRT.

That was left over in my TODO list :)

Hmm, it wasn't quite this simple - it's now picking up the iframe code path for mainframe position: fixed divs =D
