Thanks for your report. It is not possible to know how to reproduce or verify this issue from your description. This could also be the normal / expected behaviour based on the design of your creation. It is very difficult for us to investigate speculative issues but are happy to look at any issue with a clear and simple example.

It could be that you are just out of range of the tooltip ray for example.
