Blink (Chrome Canary 41) will not move focus to the input element in the ShadowRoot
of an
ShadowHost
with [tabindex="-1"]
, but it does properly focus the input element
for ShadowHost
with [tabindex="0"]
. Gecko properly handles both.
Hit Tab to advance in sequential navigation. Click on the last div and hit Tab to see that without ShadowDOM sequential navigation works fine.
