For an unknown reason my chrome developper tools device toolbar has started acting strangely when testing responsive mode. When toggling it ON, the website is completely zoomed out, the dimensions of the page are not the one displayed in the toolbar, and the layout will not adjust responsively :
When I'm toggling the device toolbar OFF, it works fine, I can resize the window and the layout will adjust responsively.
Chrome version : Version 96.0.4664.110 (Build officiel) (64 bits)
Note : I picked the google website as an example but it's the same for some page I'm working on locally.
Note 2: Same in Edge
Note 3: device toolbar works perfectly in Mozilla it seems.
