[Tracker] Icons disappear when increasing column width

[g.zachrisson@…]

Test description:

1. Open a Tracker window with the List View format.
2. Click on the resizing area between two attribute columns and keep the mouse

button pressed down.

3. Move the mouse to the left (reduce column width).
4. Move the mouse to the right (increase column width). Now the icons in front

of the filenames dissappear.

Test setup:

Haiku partition with rev17136 (with minor modifications, and old vfs.cpp).

Isn't it the same as #160

Indeed, it seems to be.
