Inline - optional from and to parameters

Presently you have to duplicate where you want to load from and to for the inline feature:

<a
        data-trimmings-inline="from: main, to: main"
        href="/cake"
      >
        Cake
      </a>
... etc
... etc

This can get pretty repetitive if you serve just a partial from the server of the exact element to be replaced.

So it would be great if the from and to were both optional and infered based on the top-root element in response from the server.

For example:

<a
        data-trimmings-inline
        href="/cake"
      >
        Cake
      </a>

Response from server:

<main>.....</main>

Trimmings will assume from: main, to: main

Another example:

<a
        data-trimmings-inline="to: custom-main"
        href="/cake"
      >
        Cake
      </a>

Assuming the same response from the server <main> trimmings will essentially assume:

from: main, to: custom-main
