Bug Report

UPDATE: see #2499 (comment) post below first

in 2.8.8 it was working, verified by reverting only the Fomantic-UI dist files

Steps to reproduce

1. open https://dev.agiletoolkit.org/demos/form/form.php (since atk4/ui@e712791 the JS files are not minified :) )
2. click Handler Safety tab
3. click Modal Test button
4. click Save button (inside the opened modal)
5. notice dimmed background but no modal window/content

Expected result

modal is open as in https://ui.agiletoolkit.org/demos/form/form.php (notice ui. instead of dev. subdomain)

Actual result

blured background, no modal shown

Version

2.9.0
