649561 - Tabs do not expand in size after a tab is closed, until cursor is moved

Status: VERIFIED INVALID

(Firefox :: Tabbed Browser, defect)

Description

[asb3480]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.2a1pre) Gecko/20110412 Firefox/4.2a1pre
Build Identifier: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.2a1pre) Gecko/20110412 Firefox/4.2a1pre

When the tabs fill the whole title bar and start decreasing in size, closing one tab does not make the others expand in order to fill in the blank space, until I move my mouse. This does not occur when I close the rightmost/leftmost tab.

Reproducible: Always

Steps to Reproduce:
1. Open a few new tabs so that they fill the title bar
2. Close one of the tabs (not the rightmost tab - that works correctly)
3. Move the mouse cursor
Actual Results:  
The tabs did not expand in order to fill the blank space that was left by the closed tab - until I moved my mouse.

Expected Results:  
The tabs should have immediately expanded in order to fill the blank space.

This is intentional - it makes closing multiple tabs at once with the mouse easier. See bug 465086.
