mouse-over on buttons doesn't work if mouse inside at button creation time

[jfortmann]

This bug affects most of the standard apps; I assume it's a bug in the GTK theme or engine.
Sample reproduction: boot from the install CD. Start the installer. Place the mouse on the "Forward" button and click it. The next pane should appear.
The forward button of the next pane is at exactly the same place; accordingly, the mouse is already inside the button's rect. Nevertheless, the button doesn't light up, and clicking it does nothing. Only after moving the mouse out of the buttons rect, then moving it back in, can the user actually click the button.

This is extremely annoying, since in the overwhelming majority of cases, the defaults in the installer are actually correct, and the user could just click through. Due to the bug, the user has to move the mouse away from the button, then find it again.

Proposed fixes:
firstly, buttons should, on creation time, check if the mouse is inside their rect, and adjust their lit-up property accordingly (currently, they obviously assume the mouse is outside).
secondly, if the user clicks the button, it shouldn't matter if the button was lit up previously. Since the user clicked the button, the mouse was obviously in. If it wasn't lit up, that's a bug, but nothing that should matter for the current state of affairs.

The bug occurs in all GTK apps; ones with assistants are just the most annoying, which is why I chose the installer as a sample.

I see this too across different themes, so I would suspect it's a gtk thing.
