Same fix as sso-manager-node: formAJAX's loading indicator passed a raw
<div class="spinner-border"> string to app.messages.action, which
HTML-escapes its message by design (@simpleworkjs/frontend) -- so every
form submit briefly showed the literal markup as text instead of a
spinner. Replaced with plain text ("Saving…").
