Description

browser: Safari external dependency scope: text field
Steps to reproduce

Link to live example: (required)
Go to the TextField demo page on MUI’s website.

Steps:

  1. Type some text into any TextField component.
  2. Click above the input area, especially outside the text’s line-height area (e.g., towards the top of the field).

3 .Observe the cursor behavior—it should ideally position itself where you clicked but instead jumps to the beginning of the text. Unless you click in the small native input line height.

Current behavior

When using the TextField component, clicking within the input area but outside the default line-height (e.g., in the top half of the input area) causes the cursor to jump to the beginning of the text instead of positioning where the click occurred. This behavior causes the input field to respond in an unexpected and inconsistent way for users.

Expected behavior

The cursor should appear at the exact location where the user clicks within the input area, aligning with standard input field behavior and enhancing user experience.

Context

This issue affects the user experience by causing unexpected cursor jumps within the input area. It occurs even with the default TextField styling, making it a general issue in applications that use MUI’s TextField component.
