Describe the bug

When the autocomplete input is disabled, the tabindex should be set to -1 to prevent tabbing into the input field.

I’ve noticed that while inputs correctly handle the tabindex when disabled explicitly, the autocomplete input has a specific behavior (maybe other ones as well) where, if the options array is empty ([]), it automatically disables the input.

However, in this case, the tabindex is not updated, allowing users to still tab into the disabled input, leading to a confusing experience

Steps to reproduce:

1. Set the autocomplete input with an empty options array ([]).
2. Try tabbing through the page.
