Component doesn't render as expected

[UltimateUnicorn]

Describe the bug
The component doesn't render as expected :

• When no file is selected the label for the field stays (far) above the field -> see screenshot
• When a file is selected the "clear" icon isn't displayed though the underlying button does

To Reproduce
Steps to reproduce the behavior:

1. Set-up a new Next.js project : npx create-next-app@latest
2. Copy the author's example into a new page
3. Run the project

Expected behavior
I believe the component should render / behave identical to the examples provided on the project's website.

Screenshots
This screenshot illustrates the first issue : no file is selected but the "File" label stay far above the component, though it should be "inside" the selection field.

This one illustrates the second issue : when a file is selected the "clear" icon is not displayed, though the button is rendered (not visible on the screenshot)

There are no issues when checking out the author's website

Hello !

Could you please provide a codesandbox for repro ?

[UltimateUnicorn]

Hi Victor ! I've pushed my project to GitHub and imported it into codesandbox.
Here is the https://codesandbox.io/p/github/UltimateUnicorn/sogeco1/main

On the left you'll find a navigation drawer with, at its bottom, a link called "mfi". It lead to a page where the issues I mentionned are being visible.

I believe both you and I are, and therefore speak, french, but keeping going in english might help a couple other people ?

Hi Victor ! A couple remarks :

• When I use the codesandbox you provide the link for in the documentation for your component I face the issue with the clear icon not being displayed.
• In my project, if I manually set the "clearIconButtonProps" with the "ClearIcon" from MUI then the icon shows up properly. I understood that I shouldn't need to set this prop for a default icon to show up. Was I mistaken ?

I can't access to your codesandbox :/ Looks like it's private

Hi. Sorry for that. I've updated the visibility of my repo and the link in the previous comment as well. Thanks for your help.
