[FLEX-23381] Releasing the mouse outside of the application does not trigger a release event for scrollbars in Firefox when wmode is set to opaque or transparent

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Not A Problem

• Component/s: mx: General
• Environment: Affected OS(s): Windows; Affected OS(s): Windows XP; Browser: Firefox 3.x; Language Found: English

Description

Steps to reproduce:

1. Create a new MXML application and add a TextArea component with some text that forces it to scroll vertically.

2. Compile the application with an HTML wrapper.

3. Add the following code to the HTML wrapper to force the wmode to opaque:

AC_FL_RunContent(
"wmode", "opaque",
...

4. Open the HTML page in Firefox.

5. Click on the vertical scrollbar thumb and start dragging.

6. Release outside of the swf, or the outside of the browser window itself.

Actual Results:
A release event is never passed to the scrollbar so the thumb is "stuck" scrolling even though the mouse has been released.

Expected Results:
A release event would be triggered and the scrollbar would stop scrolling.

Workaround (if any):
None known.

Additional Notes:
I believe this is related to SDK-12415, and is not likely limited to specific OS or Firefox versions, although it's worth noting that IE 7 works as expected.
