I was checking the form element for the first time when I encountered some bugs.
1- Immediately after selecting the icon in the submit button, the default text (send) is removed. Therefore, we must add the send text again. It would be much better if this did not happen. In fact, this behavior is not expected.
2- After clicking the button button, the width of the button increases for no reason. In fact, when the spinner is added, it creates a gap that is too much.
3- It’s not a bug, but I hope this can be done, but please add the possibility to use a custom icon for the spinner in the submit button.
