Autocomplete list overlaps with input label

[raed667]

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

When I open the autocomplete list and the layout is such that it opens to the top. The list partially overlaps with the input label.

Expected Behavior 🤔

The expected behavior is that the label isn't hidden when the autocomplete is open.

Steps to Reproduce 🕹

Steps:

1. Go to official documentation page https://mui.com/components/autocomplete/
2. Scroll in such a way that the autocomplete will open to the top
3. Click on the autocomplete input.

I suggest to add margin-bottom: 8px to the paper element, that should work and does not affect other cases.

I would consider it a bug, the proposed changes look good to me. Let's just test that all scenarios with all variants look good after the change

What happens if the input used is the filled or standard variant? Some could argue it's a bug with the OutlinedInput, not the Autocomplete: #13253 (comment). I'm not sure. Actually, maybe the popup should use the window's space, not the viewport' space to change its placement: #21661, reducing the impact of this bug.
