QtWebKit version 2.2.1 Whenever I have a text field selected and middle click on the scroll bar to scroll to a particular part of the page, the text from my clipboard is pasted to the text field. Reproducible: Always Reproducible with: rekonq, arora, qupzilla Steps to Reproduce: 1. Select and copy the title of this bug report 2. Resize browser so the scroll bar is visible 3. Click on the comment text area in this bug report 4. Middle click on the scroll bar 3. Middle click on the scroll bar Actual Results: The scroll bar jumps to the clicked location, then jumps back and the copied text is in the text field. Expected Results: The scroll bar jumps to the clicked location, stays there, and no text is pasted

Created attachment 143305 [details] Patch with fix and improved layout test I had a look into this and think that the clipboard handling should simply not be executed when the event was already handled. When checking how to make a layout test for this, I stumbled upon an existing one. But this was a PASS all the time (at least for the Qt version). So I changed the test to be a bit more like the use case described in this bug (using an <input> field). Now it correctly switches from FAIL to PASS when the change in qwebpage.cpp is applied.

Comment on attachment 143305 [details] Patch with fix and improved layout test The patch (again) looks correct to me, but I would really like to see a slightly more elaborate explanation in the ChangeLog why the change in the layout test makes it more sensitive to triggering this bug. Since this is a cross-port/platform layout test it may not be obvious, especially not when looking at the ChangeLog in three months and all we see is "made it more sensitive" :)

Created attachment 143770 [details] Patch with more elaborate LayoutTests ChangeLog Ok, a reasonable request :-) I tried to explain the changed test a bit more in the ChangeLog. What I manually tried, besides the Qt case, was a recent Chromium build. For Chromium the original test seemed to work, but the new one works, too. I am not sure if the not-triggering of onpaste on the non-editable <body> is another bug in Qt? I did not find something like a specification for onpaste... as far as I could see it was originally introduced in Internet Explorer, so it's probably not well specified. FWIW Firefox did not trigger onpaste for <body> either. Just for my education: All green EWS bots should indicate that the changed test does not break any of the tested platforms now, right?

(In reply to comment #3) > Just for my education: All green EWS bots should indicate that the changed test does not break any of the tested platforms now, right? It merely indicates that the patch _builds_ on those platforms. Only the chromium EWS is fast enough currently to also _run_ the tests (unless that test is skipped). So this should probably be landed manually with care.

So this should probably be landed manually with care. Ok, thanks for the info. So how will this proceed? Can you do the manual landing or shall I just ask "someone" on IRC?
