I am able to reproduce this bug in Safari 16.4.1 & WebKit ToT where ALT text is not respecting vertical writing mode. Chrome Canary 115 and Firefox Nightly 114 works fine.

Sadly the test case won't produce any alt text as it is too long and it covers the broken image icon (shorter text will paint fine).

(In reply to zalan from comment #4) > Sadly the test case won't produce any alt text as it is too long and it > covers the broken image icon (shorter text will paint fine). Sorry to bump but we have WPT test for long ALT Text here: http://wpt.live/html/rendering/replaced-elements/attributes-for-embedded-content-and-images/input-image-inline-alt.html Which we are failing even after this patch on WebKit ToT. Just highlighting something you mentioned. Happy to create new bug to track this failure.
