Bug 47458 – [Qt] Cannot scroll iframe with "overflow: hidden" using scroll wheel

• Component: WebCore Misc.
• Status: RESOLVED WORKSFORME

[Yael]

It is not possible to scroll an iframe with style="overflow: hidden", using the scroll wheel.
I saw this bug only in QtWebKit port (tested on Ubuntu). Safari and Chromium  (Windows and Ubuntu) do not have this issue.

Works for me with WebKit trunk. Any more info to reproduce the issue?

Benjamin, how do firefox or webkit-based browsers work here? it might be better to compat with them

Here, I can't see any difference between QtWebKit trunk and Safari Trunk, both ignore the overflow attribute.

For me, Firefox handle iframe incorrectly. It considers the element as a block layout, even though the suggested stylesheet does not defined them as such: http://www.w3.org/TR/CSS21/sample.html

In my opinion the overflow should not apply on iframe.

Sorry guys, I compared the behavior of QtWebKit to an old version of Chromium, and filed the bug due to a difference in behavior.
After updating my Chromium build, they behave the same, and I don't think this is a bug. I'll close it shortly, and sorry for the inconvenience.
