Feature: aggregate slot content for "within" queries.

[KonnorRogers]

<my-wrapper>
  <div slot="start"><button></button></div>
</my-wrapper>

within(wrapper.startSlot).getByShadowRole("button")

^ should return button, but due to how projection of slots work, it doesn't.

this is a simple example but more complex reasoning may involve finding a specific row of a table which may have many slots.

This is still an open issue, correct? I tested a within query after v1.10.0 and it still didn't work. It's now really hard to debug why exactly it's breaking since there's so much magic happening in this library. 😅 Great when it works, terrible when it doesn't! haha

This should work, however, hard to know without seeing something to reproduce

[CreativeTechGuy]

I'll see if I can make a minimal reproduction. The general idea is something like this:

<my-table>
    <ShadowDOM>
        <tbody>
            <tr>
                <td>
                    <slot name="cell-1"></slot>
                </td>
            </tr>
        </tbody>
    </ShadowDOM>
    <a href="/dest" slot="cell-1">MyLink</a>
</my-table>

And then my query is:

within(tr).getByShadowRole("link", { name: "MyLink" });

Let me know if this helps at all or if you need more info.
