Subject: [PATCH] Make <img>.complete more reliable

These changes are in line with all three browsers. Chrome still diverges significantly from the standard & tests though on other aspects.

Tests: https://github.com/web-platform-tests/wpt/pull/19298.

Fixes #1055, fixes #4475. #4476 remains outstanding.
