591754 - Can scroll window with mousewheel while alert dialog is open

Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

Description

[Martijn Wargers (dead)]

Attachment: testcase

See testcase, an alert opens up when visiting that page.
When using the mousewheel while that alert dialog is open, the page scrolls.
That should not be happening.

This works in a 2010-08-17 build, but fails in a 2010-08-18 build, so I think a regression from bug 130078.

You are right, I assume, that the design is such that it should not happen.

However, this seems like a useful feature.
Rather than preventing the user from scrolling (or whatever) it would seem better if the browser merely prevented the (content) JS context that spawned the alert from receiving events (until the alert closed).

Our tab modal alerts seem to have addressed this. RWFM?

It probably still happens.

Not reproducible in Windows 7 with latest Firefox 46 RC and with latest Firefox nightly 49.0a1.
Considering this, I will mark this issue as Resolved-WORKSFORME. 
If anyone can still reproduce it, feel free to reopen the issue and provide more information. 
Thanks
