Ajax Comment: Page reloads whenever the comment submission form is reloaded

I found out the issue. It was something like jQuery/AJAX code for it is not being able to hook itself when I reload the form with .load(), therefore the second time I submit a new comment, or when I clicked the reload button for the comment list/form (making the .load() run once), the new form would still submit the comment but since the jQuery/AJAX is not being run, the page reloads normally without AJAX.

I just changed the code from this:

$('#commentform').submit(function() {
  .....
}

to this:

$(document).on('submit', '#commentform', function() {
  .....
}

I’m glad that I’ve been able to pinpoit the issue, even if it took a long search and carefully selecting my search keywords on google.
