Wrong position of tooltip arrow when 'constraints' moves the tooltip

Issue #20685 was closed but this is not an issue with tether.

If your tooltip is moved due to constraints (ie. to keep the tooltip on the viewport), the arrow no longer points to the target element. This has nothing to do with tether as said in #20685 and everything to do with the use of ::before elements positioned left: 50%;.

Check out the originally supplied jsbin and you'll see that there is nothing tether can do to fix this.

Currently we removed the use of Tether and now we use Popper.js and Popper.js manage the arrow position so this issue don't exist with latest v4-dev dist files.

X-REF: #22681
