Unhandled expection in ix-tooltip

Prerequisites

[X] I have read the Contributing Guidelines.
[X] I have not leaked any internal/restricted information like screenshots, videos, code snippets, links etc.

What happened?

I did not confirmed this but my best guess is that when an ix-tooltip's anchor element can not be found then the error is not handled.
