[4.x]: Twig template not found using action elements/save-draft in frontend

[swordinthestone]

What happened?

Description

When using ajax or direct form post with an action "elements/save-draft" from front end, action return a template error "Unable to find the template “_includes/forms/text”". I am using this action to save a draft for existing entry to provide a preview to end user.

The error is occur on
src/controllers/ElementsController @ Line 1151

$form = $fieldLayout->createForm(...)

This action is loading templates from front end template folder, instead of vendors folder, to bulild response. Actions works as excepted from control panel.

After reading the sourece code, I am not sure it is intended to process this way or not, because it makes sense to build form tabs on control panel. However, as Craft 4 has change "entry-revisions/save-draft" to "elements/save-draft", and seem like there is no other alternative actions to save draft from front end nativly from Craft.

Therefore, my question is:
Should action "elements/save-draft" be only used on developing custom control panel plugins? We should write custom action to handle element draft for front end.

Steps to reproduce

1. Form submit from front end with action "elements/save-draft" with proper elementId, Element types and other required data, even using exact same payload for Preview.

Expected behavior

Can return an response as action from control panal to save a draft.

Actual behavior

Draft is not created in database, because the form render error interrupt the response building process.
