I have a component with a textarea input.

I noticed that if the text area has new lines in the start or end of its content and the component is re-rendered, it will remove these new lines.

When looking into the form structure, I noticed these fields:

%Phoenix.HTML.Form{
  source: #AshPhoenix.Form<
    ...
    params: %{"male_content" => "\n\nline\n\n"},
    source: #Ash.Changeset<
      attributes: %{
        ...
        male_content: "line",
        ...
      },
    >,
  ...
  params: %{"male_content" => "\n\nline\n\n"},
  ...
}

As you can see, the params field, both for Phoenix.HTML.Form and AshPhoenix.Form has the new lines correctly, but the Ash.Changeset doesn’t.

I’m guessing that when the re-render happens, the form will replace the textarea content with what is in the Ash.Changeset and remove the new lines.
