Font Awesome SVG mode freezes ACF New Post Type creation

Beta
#1

If I try to add a new custom post type via ACF the browser freezes after clicking Add New Post Type.

I think it is related to the SVG Icon Type setting and the ACF Icon Picker tabs added in Pro 6.8.11. Loading the entire icon catalogue into the HTML as data-icons attributes, for every enabled FA style seems to much to choke on for the browser.

Steps to reproduce

  1. Set Font Awesome Icon Type to SVG.
  2. Have ACF PRO 6.3+ active.
  3. Go to ****** Custom Fields → Post Types → Add New ****** (/wp-admin/post-new.php?post_type=acf-post-type).
  4. The tab becomes unresponsive for a long time; on slower machines it stops responding entirely.

Workaround

You already ship a switch, which disables the tabs completely. Only works, if you do not need FA Icons in ACF:

add_filter( 'cs_acf_fa_tabs_enabled', '__return_false' );
