Hello, first of all: Thanks for this awesome project.

I think my situation might be linked to #648 , but I'm not sure, as the pieces of code that was provided into that thread is not accessible anymore.

My situation:

I got an HTML table, like this

<table>
    <!-- headers and all -->
    <tr id="row-103"><!-- row content --></tr>
    <!-- other rows -->
</table>

Each how has an "edit associations" link, which opens up a form into a modal and loads some content.
This form is rendered like this:

<form
    action="http://localhost/edit associations/103"
    method="post"
    up-submit="up-submit"
    up-layer="root"
    up-target="#row-103"
    up-match="first"
    up-fallback=".content"
    class="up-can-clean">
<!-- form content -->
</form>

When the form is submitted, the server returns:

<tr id="row-103"><!-- row content --></tr>

But I'm getting this error:

Uncaught (in promise) up.CannotMatch: Could not find common target in current page and response (tried selectors [#row-103, .content] in layer "root")

I put the .content into the up-fallback to inspect the HTML from root. If I don't use it, it does not throw the error, but replaces the body with the tr content (without the tr tag itself).

Because I could not overcome this, I created a very simple project to debug the issue.
In this simple project (with super simple HTML) it works as intended. In this simpler project I did not use up-match. It just worked.

I also tried to put some breakpoints into unpoly's code to understand why it's not being able to match and swap the tr elements, but I was unable to come to a conclusion, because when I use up-match first, I can debug to a point where it matches it in response and in document, but it keeps trying to match and I could not get the point when it does not match anymore.

Could someone shed some light into it for me?

Thank you!
