Reviewed by Tim Nguyen.

This patch aligns WebKit with Blink / Chromium and Gecko / Firefox.

Merge: https://chromium.googlesource.com/chromium/src.git/+/350b1fecbdea7310b122e3e83c67929fa282d754

If value="" is specified on an image-type form control then use "" as the alt-text
for the control if one is required. This matches Firefox and Edge, also IE11.
