    <thetext>Bug 20247 is still an annoying thorn for development, as it is just *awkward* to see non-bubbling events dispatch to ShadowRoot hosts.

Given that this property is a compromise compliance for the event capturing phase, can we instead just drop the ability to capture events through a ShadowRoot boundary?

It seems rather unlikely that a developer using capturing events will handle events fired inside of a ShadowRoot correctly, and it seems a beneficial property of closed ShadowRoots to close another loophole through which information can leak.

WDYT?</thetext>

    <thetext>I am feeling that we should have one good idea which resolves this bug (bug 28246), bug  26892 and bug 20247, all together.</thetext>
