2 issues were found when an iframe does not contain any visible focusable elements, but does contain focusable elements that are outside of the view. 1. The iframe scrolls to the first focusable item and the text part of it cannot be scrolled into view. 2. When items under the iframe are focused, and trying to scroll up, the iframe never gets focus. The first issue does not exist in Opera's implementation of Spatial Navigation. The second issue is a bug in Opera as well, but obviously users would want to be able to scroll into the iframe :-( Here is an example page for this bug: main page: <html> <body> <iframe src="frame11.html" width=300 height=50></iframe><br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> </body> </html> iframe: <html> <body> This is filler text 1<br> This is filler text 2<br> This is filler text 3<br> This is filler text 4<br> This is filler text 5<br> This is filler text 6<br> This is filler text 7<br> This is filler text 8<br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> <a href="#">This is a element</a><br> </body> </html>
Both issues are known and real. (2) Is really a web design fault, and I think we should not carry much (see that even Opera fails) (1) is a _must_ fix, yes.

(In reply to comment #1) ... specially because frame flattening fix this :)
