wpbakery text block issues after updating dokan lite

hi team,

i have an issue related to dokan after updating to version 2.8.0 , and it still there in version 2.8.1
before those two versions it was working so the issue is not for pro version it’s for lite version and if it fixed by a pro version update it will be just a work around,
the issue happens with wpbakery latest version installed while editing any page i used text block in it.

here’s chrome console errors while editing a any page and i can see it’s specifically related to dokan and tinymce

JQMIGRATE: Migrate is installed, version 1.4.1
