Tooltip is a function loaded via the heisenberg_all.js on jQuery. If this js script file(heisenberg_all.js) is not loaded on the CMS, you will see the above-mentioned error in browser console.
One possible cause of this issue is glide.ui.heisenberg.exclude property's value is set to "view_content".


Remove/delete the property glide.ui.heisenberg.exclude
