[InputBase] Suggested attributes of inputProps don't show HTML input attributes

[mgirondo]

• 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 trying to get suggestions for the inputProps prop on InputBase, it is not showing HTML Input Attributes, such as maxLength.

However, these props are actually passed to the input element.

Expected Behavior 🤔

It should show the available attributes for input HTML elements, not only global attributes.

Steps to Reproduce 🕹

Steps:

1. Demo
2. Start typing on inputProps to get suggestions
3. Find out only Global Attributes are shown

Context 🔦

I was trying to pass maxLength attribute to inputProps in <InputBase /> and couldn't get it suggested.

Is there any reason to have InputBaseComponentProps interface extending React.HTMLAttributes and not React.InputHTMLAttributes on InputBase.d.ts?

[michaldudak]

The InputBaseComponentProps effectively accepts React.HTMLAttributes<HTMLInputElement | HTMLTextAreaElement> & Record<string, any> meaning you can basically put there almost any object, but at the cost of having exact suggestions. We are discussing the approach for typing inner components' props in #27499
