Error on tooltip for dynamically added marker in 1.6.0

[ishaiavrahami]

When hovering over the regions im not getting any errors. However, after adding a marker dynamically and then hovering over it it works, but throwing an error in console. I suggest adding ?. when nesting. See pic below

Hi @ishaiavrahami

Can you provide an example that reproduces the issue, I tried to implement an example depending on the given steps but I can't see an error.
