1434149 - overflow menu shows only half of a browser_action popup with long title

Status: RESOLVED DUPLICATE of bug 1373490

(WebExtensions :: Frontend, defect)

Description

[Andreas Klauer]

Attachment: long title causes popup to be cut in half (red line added to illustrate)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20180103231032

Steps to reproduce:

Take any webextension with browser action popup (e.g. https://github.com/mdn/webextensions-examples/tree/master/user-script )

Edit manifest.json (or call browserAction.setTitle) to set a slightly longer title, for example "default_title": "User script and what happens if the title is too long to fit",

Load the extension, right click the browser action icon, Pin to overflow menu (or alternatively, make the browser window a bit smaller so it goes into overflow menu on its own accord)

Click overflow menu, browser action icon, and...


Actual results:

...only half the browser action shows up (see screenshot)


Expected results:

...popup should show up normally.

Alternatively limit the allowed length one may set as a popup title.
