Submitting a form with [target=_blank] ignores the target

[martinzamuner]

When submitting the following form

<form id="targeted-form-post" method="post" action="/__turbo/redirect" target="_blank">
  <input type="hidden" name="path" value="/src/tests/fixtures/one.html">
  <input type="submit" id="form-post-submit" value="Submit with target"/>
</form>

Turbo treats it as a normal submission and ignores the target. If data-turbo="false" is added to the form, it behaves as I would expect, triggering the submission from a new tab/window.
