Go to www.okcupid.com 2. Fill out the form on the first page and click "Next" 3. Click on either the zip code or email address field 4. Type in one or more letters Actual Results: The content pane will pan to the top left Expected Results: The content pane shouldn't move

I've seen this happen on other websites too (bugzilla as example). I think this is relate to scroll position or something like that because I can see a scroll event happening when typing a letter which cause the UI to redraw at position 0,0

also matchage.com when typing the age in the text field

Happens (at okcupid.com and matchage.com) with both 1.9.2 and trunk nightlies 20091125 on linux-i686. At matchage.com, it doesn't happen every time with the 1.9.2 nightly.

I see this on bugzilla's frontpage when typing text into the "Quick Search" below the large button images. This probably needs to block.

I've kept this bug opened just to remenber it also affects the Form Assistant.

dupe v.

Because there is a reflow when you enter a letter on the keyboard and because the real browser scrollbox position is at 0,0 we handle it thought handlePageScroll. This patch fix that but it also means that we're going to handle page scroll events when while the form assistant is opened.

Ben, this bug is the real bug which correspond to 527187 which is a blocker (and a dup of this one)

Comment on attachment 416653 [details] [diff] [review] Patch >+ _ignorePageScroll: false, >+ ignorePageScroll: function ignorePageScroll(aIgnoreScroll) { >+ this._ignorePageScroll = aIgnoreScroll; >+ }, Oh noes :( I'm pretty certain there is no other way to do this, so you get an r+. Fixes the problem for me on okcupid.

Ben I have filled bug 533970 for the bug you found during the test for this patch
