Summary Resetting the value of an input file to null should make it invalid

I'm trying to select an input[type="file"]:invalid but it doesn't work on Safari. That's because Safari doesn't mark it as invalid when this FormElement value is reset to "" or null. Isolated preview: https://codepen.io/FelipePS/pen/OJvJmoK How to reproduce error: 1) On load, input is invalid (background-color light blue) because it's empty and required. 2) Add a file to it. It changes to valid as expected, assuming background-color light grey. 3) Click "Remove file" to reset the input. Expected behaviour: Upon clicking "Remove file", it should assume background-color light blue again, because it's now empty and it's a required field. Chrome 102 and Firefox 100 behave as expected. Current behaviour: Safari maintains the input field as valid (background-color light grey).

Found a simple workaround! call setCustomValidity(" ") with a non-empty string to manually make field invalid.
