QLineEdit:hover { background: blue; } only changes color when it has focus

When creating a 

QLineEdit *inputLine = new QLineEdit(this);
inputLine->setStyleSheet("QLineEdit:hover {background-color: blue;} QLineEdit {background-color: green;}");

and setting the style sheet to change color when hovering it does not change color on Windows except when first clicking on that line.
This is what currently happens:

However when I click on a box it does work for that box:

But on Linux I get the expected result. When I hover over the boxes without click, it changes color:

 
I am not sure why this happens. I also tried the same with QSpinBox and on Windows the issue is not there and it behaves the same as the QLineEdit on Linux.
