Status: ASSIGNED

Description

[Jonathan Almeida [:jonalmeida]]

STR (from Arturo):

1. Enable remote debugging
2. Go to https://www.w3schools.com/jsref/met_win_alert.asp
3. Click the button "Try it" an alert dialog should show.
4. On your desktop browser, open that tab on about:debugging
5. Go to the console tab
6. Navigate to another website while the dialog is opened window.location = "http://www.mozilla.org";

Expected behavior
After 6 we expected a call to onPromptDismiss

Actual Behavior
onPromptDismiss is not called

This stemmed from a sec bug that found these STRs were not covered by the onPromptDismiss.

FWIW I think this is a feature request more than a bug, this never worked before.

Attachment: Bug 1749398 - Dismiss prompt when pagehide is received.

When modal dialog is shown then page navigation is invoked, onPromptDismiss
isn't called yet. We have to consider this situation.
