Loading prop has no effect

[swfsql]

First thanks for working on this lib! I'm a newcomer trying it out.

I believe the loading prop for TextArea has no effect, as the loading spinner animation exists in a html ::after that is present when a is-loading class exists in a control wrapper element.

The following rust:

<ybc::Field
    label={".."}
    help={".."}
><ybc::Control
    tag={"div"}
    classes={classes!("")}
><ybc::TextArea
    name={"example"}
    value={""}
    update={link.callback(Msg::TextAreaUpdated)}
    placeholder={".."}
    loading=true
/></ybc::Control></ybc::Field>

Results in the following html (in which the spinner is not present) :

<div class="field">
  <label class="label">..</label>
  <div class="control">
    <textarea name="example" placeholder=".." rows="0" class="textarea is-loading"></textarea>
  </div>
  <label class="help">..</label>
</div>

Note: the .field.control.is-loading is set.

But the following rust:

<ybc::Field
    label={".."}
    help={".."}
><ybc::Control
    tag={"div"}
    classes={classes!("is-loading")}
><ybc::TextArea
    name={"example"}
    value={""}
    update={link.callback(Msg::TextAreaUpdated)}
    placeholder={".."}
/></ybc::Control></ybc::Field>

Results in the following html (in which the spinner is present) :

<div class="field">
  <label class="label">..</label>
  <div class="control is-loading">
    <textarea name="example" placeholder=".." rows="0" class="textarea"></textarea>
    ::after
  </div>
  <label class="help">..</label>
</div>

Note: The .field.control and the .field.is-loading are set.
