Form ID – backend / frontend

Previously, the form ID in the HTML tag would correspond to the form ID (shortcode) in wp-admin.

I noticed that now they are not synced.

For example, in the frontend the tag would be

<div class="wpcf7 js" id="wpcf7-f56-p12-o1" lang="en-GB" dir="ltr">

and the shortcode is:

[contact-form-7 id="96a8715" title="Contact form 1"]

any reason for that? Is there a good way to connect between the form on the frontend and the shortcode in wp-admin.

This is especially important when there are several forms on site.

Thanks,

Dan
