[css-flexbox] Migrate bug605682.html test from css3/flexbox to WPT

mariospr · chromium-wpt-export-bot · commit 28f5209e3021 · 2020-03-31T05:31:29.000-07:00
Migrate this test out of third_party/blink/web_tests/css3/flexbox and into the WPT-specific directory, adding links to the relevant specs and a test assertion describing its purpose. Also, rename its filename to something more descriptive and less Chromium-specific (it currently references crbug.com/605682).
