770346 - Dragging an SVG Element becomes unresponsive

Status: RESOLVED INVALID

(Core :: SVG, defect)

Description

[Patrick]

Attachment: firefox.php

User Agent: Mozilla/5.0 (Windows NT 6.0; rv:13.0) Gecko/20100101 Firefox/13.0.1
Build ID: 20120614114901

Steps to reproduce:

Dragging an SVG circle seems to response well on drag at first, but after a few seconds and some random mouse clicks/moves it seems to ignore and mix up mouse events. 


Actual results:

element gets dragged while mousebutton is not pressed, and visa versa


Expected results:

the drag should finish on mouse up. This problem does not  happen with other browsers.

Extensions doesn't matter

Are you calling preventDefault on the event argument in all your event handlers?

No, I've included the sourcecode in the attachement. I'm just using 3 mouse events (mousedown,mousemove and mouseup).

I know, but changing it to html you could run it straight in the browser without the need for running a webserver. :-)

Can anyone confirm the bug?

You need to call evt.preventDefault() in the event handlers to prevent any default event handling.
