OSX Big Sur 11.1 reverts size of open/save windows

When using the open/save function (opening a window) I resize it to reflect my needs.

A sidebar with sufficient width to read my folder names and a larger window at all to be able to navigate through folders.

In previous versions of all OSX-versions if I recall it correctly, including Big Sur 11.0 this resized size became the new standard. 

With the latest install of Big Sur (11.1) the open/save window reverts to a standard size. 

So now I have to resize the window every time I open/save files.

This happens on all Apps and Finder

This is a pain in the *** to say it nicely and overlooked by Apple QA

Fix it
