1329936 - WebExtensions: Popup size set to 0px x 0px when apz.allow_zooming is enabled

Status: RESOLVED DUPLICATE of bug 1560770

(WebExtensions :: Untriaged, defect)

Description

[dw-dev]

Attachment: Zoom Page WE popup shown with width: 0px and height: 0px

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161104212021

Steps to reproduce:

1. Installed my Zoom Page WE add-on.
2. Set 'apz.allow_zooming' to 'true' in about:config preferences.
3. Click on add-on toolbar button to display the popup.
4. The popup is displayed with zero size (width: 0px and height: 0px).

This happens because the <browser element class="webextension-popup-browser"> element (inside the <panelview> element) has a 'style attribute with width: 0px and height: 0px.

This problem is very likely related to the fix made in Bug 1215025.


Actual results:

The popup is displayed with zero size (width: 0px and height: 0px).
See attached screenshot.


Expected results:

The popup should have been displayed at the correct size, as it is if 'apz.allow_zooming' set to 'false'.

This is not a supported configuration on desktop. We'll handle it if and when that changes.
