Slot element with tabindex=0 that generates a box should be focusable

In Chromium, the <slot> element that is generating a box (i.e. overriding the default display: contents) and has its tabindex attribute set to 0 in this structure cannot be focused by tabbing. In Safari and Firefox, this works fine.

<div>
    <template shadowrootmode=open>
        <slot tabindex=0 style="display: inline-block;"></slot>
    </template>
    Content
</div>

I’ve started creating a failing test for this, but I’m going to need some help fixing it as I can’t get it to not timeout. I’ve borrowing utilities from other tests in the same /shadow-dom/focus/ directory as well loosing following some of the other tests.

If this seems like expected behaviour I’ll follow up with a bug report to Chromium, otherwise, I’ll file bug reports for Safari and Firefox.
