Status: RESOLVED DUPLICATE of bug 974389

(Firefox :: Menus, defect)

Description

See the attached screenshot.

If there's enough space on the left, the new Australis doorhangers overflow out of the window.

Steps to reproduce:
1. Open Customizing mode
2. Move some buttons with dropdown doorhangers (*) to the left of any toolbar (Menu Bar/Tabs Toolbar/Navigation Bar/Bookmarks Bar/Add-on Bar (if restored))
3. Close the Customizing mode
4. Move the entire non-maximized window slightly to the right, so there's enough space between the left screen border and the outer left window border
5. Click the buttons.

Expected results:
Doorhanger detects it's too close to the inner left window border and opens to the right (like #12 does).

Actual results:
Doorhanger opens to the left, even if there's enough space on the right (screenshot #1-8, see #5).


(*) Affected buttons: Developer (#1), History (#2), Feeds (#3), Downloads (#4), Sidebars (#5), Character Encoding (#6), Edit Bookmark (#8) & Bookmarks Menu (#7).

#9 is fine, because there isn't enough space on the right. Also see #10, #11, #12, and #13 - these are always contained within the window, so they are fine.

Reproducible: With the mentioned buttons, always.

Tested on the latest Nightly (32.0a1 (2014-05-27)) and latest Stable (29.0.1) on Windows 7 Pro x64 SP1.
