314087 - Focus() to input field scrolls document to top

Status: UNCONFIRMED

(Core :: DOM: Core & HTML, defect, P5)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b5) Gecko/20051006 Firefox/1.4.1

Using the attached .html and javascript, scroll down below the "Rows" and click on "Click here to edit and scroll".  This is a degenerate version of an inplace-editor javascript from script.aculo.us.  It hides the <P> element, and inserts a <form> and <input> element directly before the <P>.  It then attempts to select() the new input field.

When I call select(), Firefox 1.0 immediately scrolls to the top of the page.  Firefox 1.5 blinks and then focuses on the input field.  Other browsers (IE, Safari) go directly to the input field.

If you instead click on "Click here to edit without scrolling", you'll call a very similar routine that uses setTimeout() to wait 1 ms before calling focus().  That does NOT scroll or blink; it works as intended!

Similarly, anything that will cause a delay - an alert() box, or stepping through with Venkman - will prevent the problem.  So I'm guessing it's a race condition that's somewhat, but not completely, better in 1.5.

Attachment: usable testcase

If you absolutely need multiple files for a testcase, please attach the dependent files first, so you can get the filename for the attachements, and then edit the HTML to refer to those files. In this case, where you don't appear to need more than one, using just one is a whole lot more convenient.
