Latest Version Bug

i use elementor page builder to for some advance work. i upgraded tinymce to 5.5.1 and the problem occur. in elementor, when i add tab or toggle block, editing settings doesnt show up in sidebar. this happens if i customize tinymce. if i use default settings, no problem.
so i rollbacked to 5.5.0 and used custom settings but this time no problem. i hope developer will check it.
