Slider not releasing mouse control in Widget Gallery Demo

[vivaladav]

When releasing the mouse button outside the active area (panel delimited by black border), it's still possible to move the slider when moving the mouse.

Steps to reproduce:

• left click on the slider
• move mouse outside the active area
• release mouse button
• go back inside the active area
• slider is still following the mouse

I can reproduce that, too. Legit bug.

May I ask how you found this project? :-)

@suy linked this repo in a chat (we all work with Qt).

And I knew it because @peter-ha "starred" it on Github. ;-)
