The php-debugbar resize handle is not working in Firefox

[ovidiugabriel]

Hello,

The php-debugbar resize handle is not working in Firefox . The initial height is very small, only 40px so 1 and a half line is visible.

Even if I temporary use the following code to adjust the debug bar height ...

document.querySelector('.phpdebugbar-body').style.height = '500px';

After using the resize handle with the mouse, it immediately snap to 40px and stays at that size.
