Status: VERIFIED FIXED

(Core :: DOM: UI Events & Focus Handling, defect, P2)

Description

[Henri Sivonen (:hsivonen)]

Steps to reproduce

1. Enable Fission (once bug 1556627 has landed)
2. Navigate to https://hsivonen.fi/fission-host.html
3. Click a text field inside an iframe.
4. Click the location bar.
5. Press a keyboard key.

Actual results

Both the location bar and the text field in the iframe look focused and paint a blinking cursor. The keystrokes go to the location bar.

Expected results

Expected the text field in the iframe not to look focused and not to paint a text insertion point bar.

The problem is that https://searchfox.org/mozilla-central/rev/91f6c02fcf4c16f78fdc4417f61f192688294066/dom/base/nsFocusManager.cpp#760 compares with mActiveWindow.
