Tooltip In PowerBI Embedded report sporadically loads or doesn't load, in the same session.

I have a powerbi embedded report, with a very simple tooltip displaying a single row of data and nothing else.
When I hover the tooltip when the page first loads, the tooltip works fine.
Then if I hover over another tooltip, such as the default tooltips for a line chart, after that the custom tooltip will hang on the loading animation. If I hover the line chart again, then return to the custom tooltip, it will work again.

Steps to recreate issue:

->Publish report with custom tooltip report page.
-> Hover custom tooltip - works as expected
-> Hover a charts default tooltip - works as expected
-> Hover the custom tooltip again - forever loading
-> Hover charts tooltip again - works as expected
-> Hover custom tooltip - working again.
-> the cycle of anguish repeats forever
