1088948 - Page Info > Media loading semantics are broken

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Stephan Sokolow]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:34.0) Gecko/20100101 Firefox/34.0
Build ID: 20141004161010

Steps to reproduce:

1. Choose "Page Info" from the context menu
2. Click the Media tab
3. Select favicon.ico


Actual results:

Sometimes, the preview pane remains blank unless the image is deselected and reselected. (However, deselecting and reselecting always works)

Given that loading sometimes works and sometimes doesn't, I get the impression it's a race condition of some sort, but I wouldn't know where, since favicons are always loaded into the tabs by the time I do this.


Expected results:

If the image isn't ready by the time the preview pane wants it, the pane should be automatically refreshed once the image IS ready.

Regression range:

I guess it's due to:
Jonathan Kew — bug 828508 - use higher-res favicons for tab titles in hidpi mode if available. r=dao

Page Info probably doesn't load the high-res favicons when the window is open.

This is still reproducing on latest Nightly (48.0a1) on Ubuntu 15.04.
