<input type="file"> controls consist of a textfield and a button. The textfield used to be tabbable, and now it isn't. This makes it difficult for a screen reader user to use the form control (read what file is currently listed there, not to mention realize that it's a file input).

If this behavioral change is intentional, I'm not sure why. It makes us different from the other browsers in a less accessible way. Being able to type in the filename without using the file picker is a good thing.
