Slider: handle jumps a few pixels when clicked

[sz_zoly7]

When clicking near the edge of the handle, the handle may jump before the user actually moves the mouse.

It seems that this bug only appears on IE and Firefox browsers.

I'm not able to reproduce this. IE8, IE6, Firefox 3.5.5.

I spoke too fast, my ​patch fixed the issue on the site I'm working on. On the demos, I still see ​the behaviour you describe.

Idea: what about using the relative position of the click inside the handle instead of ( closestHandle.width() / 2 ) ?

Also, I've found that it might have to do with the left margin of the handle. The default theme uses '-.6 em'. If you change that value, the point inside the handle where -when clicking- the bug happens, moves farther or closer to the right edge.

Hope this helps.

I've proposed a ​fix for this bug (commit). I pulled the ​slider demo and was able to make my one-line fix work in a local version of it as well as in my own project. The behavior is more universal than mentioned above. See my commit for more detail.

Slider: Modified handle and scroll content not to jump twice when handle is grabbed and dragged from anywhere other than absolute center. Fixed #4467 - Slider: handle jumps a few pixels when clicked.
