Current behavior 😯
See expected behavior first.
in v5 this does not work, and I tried a lot of different props and it does not work. Behavior in v5:

This popover over the input also happens when we have a lot of options that does not fit into screen, it's not just with resizing. I can live without the resizing part, but when I click on the input to open the menu, the popover should open always below the input.
Expected behavior 🤔
In v4 we could use this props in Select to have the menu always below the input:
MenuProps={{
anchorOrigin: {
vertical: "bottom",
horizontal: "left"
},
getContentAnchorEl: null
}}

Context 🔦
I want the same behavior as in v4
