[autocomplete] Cannot use start adornments on multiple select autocomplete #19479

Using start adornments on multiple select autocompletes makes the chips stop rendering.

Current Behavior 😯

If you try to have a multiple select autocomplete with adornment the chips won't render anymore

Expected Behavior 🤔

To have the ability to use adornments without breaking the autocomplete

Steps to Reproduce 🕹

Add InputProps.startAdornment to the params that you get on the render function, pass it onto the textField and see what happens.

1. on the first autocomplete, search and try to select options. you will see them selected when the options are shown but you will not see the chips
2. on the second autocomplete you won't even get the options to show
3. the third autocomplete is working just fine without adornments

I tried this approach with non-multiple autocompletes and it worked just fine
