Programmatic submit bypasses onsubmit/validation and the handler doesn't prevent the default, so the native submit also occurs—risking double-submit. Use: onclick='this.disabled = true; return true;'

Suggested change

Calling form.submit() in onclick bypasses onsubmit and HTML5 validation, and because the handler doesn't return false, the native submit runs too—risking double-submit. Change to: onclick='this.disabled = true; return true;' (also apply to 'Set Login Shell' at lines 250–255 and 'Request Account Deletion' at lines 288–291).

Calling this.form.submit() in onclick bypasses the form's onsubmit handler at line 150 (the confirmation) and HTML5 validation, and the handler doesn't prevent the default, so the browser will also perform the native submit—risking double-submit. Remove the programmatic submit and let the form submit naturally after disabling: onclick='this.disabled = true; return true;'

Suggested change
<input type='submit' value='Leave Group' onclick='this.form.submit(); this.disabled=true;'>
<input type='submit' value='Leave Group' onclick='this.disabled=true; return true;'>
