1448773 - Taskbar tab preview list in Aero Basic Win7 design misses favicons

Status: RESOLVED DUPLICATE of bug 1433037

(Core :: Widget: Win32, defect)

Description

[Mario *LigH* Rohkrämer]

Attachment: Firefox 58 tab preview list with generic Icons

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0 SeaMonkey/2.49.1
Build ID: 20171016030418

Steps to reproduce:

Browse websites with own favicons in several tabs in Firefox under Windows 7 (Home Premium, or a better variant but with Aero Basic design, not Glass). Hover the mouse over the taskbar button to display the tab preview list.


Actual results:

When Aero Glass is not available, there are no Aero Peek content previews, instead just a list with tab titles (that's okay), and to their left, each a "default application" icon (that's wrong).


Expected results:

The preview list of tab titles should be preceeded by the favicons of each tab. Other browsers based on older Firefox code (like Seamonkey, Pale Moon, Basilisk) display the tab list correctly, even the topmost tab is highlighted.
